Abstract

The invention relates to a system and methods for verifying a person's identity, and pertains in particular to such a system and methods which utilize comparison of a fingerprint pattern for identification verification. The image of a fingerprint of a person to be identified is provided on an inkless means which when touched by finger of the person causes immediate development of an image of the fingerprint of the finger in a black and white appearance. This image of a fingerprint is video scanned (60) to produced image data which is digitized (10) to produce a non-minutiae digitized numerical identifier indicative of the fingerprint. A preferred method and system provides a non-minutiae digitized numerical identifier having 24 bytes of fingerprint identification data which is recordable within the magnetic stripe of a credit card personal to a person, or may be recorded within the confines of a portable personnel identification means, or within a smart card, personal to a person. The non-minutiae digitized numerical identifier is provided by selectively analyzing different parts of a fingerprint and deriving from each part a byte numeric which is directly related to the ridge count computed for that part. Prior to performing the 'digitizing' method, a fingerprint identity window is defined as the area of analysis. The present invention also discloses inventive methods relating to 'image sizing' and 'image framing' which are performed upon the fingerprint image and whitespace digital data stored in memory, prior to defining a fingerprint identity window. Various applications of the invention methods and system are disclosed herein.

Description

NON- INUTIAE AUTOMATIC FINGERPRINT IDENTIFICATION SYSTEM

AND METHODS

BACKGROUND OF THE INVENTION

The invention system and related methods are directed to the automatic identification of fingerprints by video scanning and digitizing analysis of the scanned fingerprint, and to the general field of verification of the identity of a person to be identified, such verification being accomplished by comparing a non-minutiae digitized numeric identifier indicative of a fingerprint of a person to be identified with a numeric identifier recorded within the confines of a portable personnel identification means, personal to the person to be identified, which identification means can be of numerous kinds such as a retail credit card, a smart card, or others as set forth hereinafter. The numeric identifier of such portable personnel identification means is previously derived in accordance with the teachings of the present invention and then recorded within the identification means to enable identity verification, accomplished by comparison. It is most desirable to have automatic means and methods for identifying human beings. Millions of individuals are checked on a daily basis by cumbersome and unreliable methods in. banks, retail stores, classified areas, security environments, and by law enforcement officials. The problem of verifying the identity of an individual to a personnel identification card means held and offered as proof of identification by such individual, is one of the most common faced in the everyday duties of commerce, industry and government. Present day fingerprint verification methods are too time consuming and cumbersome to be expediently implemented into the civilian and military affairs of today's society. What is clearly needed is a means of, and methods for, providing automatic, rapid and positive verification of a person's identification. The system invention, and the inventive methods utilized therein and related thereto, satisfy this long felt need for methods and means for providing automatic verifiable identification of an individual submitting him or herself for identification for the purpose of: retail credit card purchases, authorized entry, check cashing, obtaining a driver's license, showing proof of age via a driver's license, verification of the identity of a holder of a passport, etc. A further great need is the development of such a system and methods for providing a verifiable fingerprint identifier which is most applicable to and recordable within a magnetic-stripe of a portable personnel identification card means, such as a magnetic stripe of a credit card. The least number of bytes within a verifiable fingerprint identifier, known to the inventors of the present invention, is a 400 byte numeric identifier developed by FINGERMATRI . This known development is not at all applicable to a portable personnel identification card of the magnetic-stripe type for reasons well known to those skilled in this art.

The presently disclosed system invention and the inventive methods thereof fully satisfy this further need by providing a verifiable non-minutiae fingerprint identifier having but 24 bytes of fingerprint identification data which affords recordability to magnetic-stripe identification cards.

The invention includes the actual taking of an individual's fingerprint via an inkless means each time an identification is to be made. The print can be taken of any digit of a person, i.e. index finger or thumb or toe, and the image of a digitprint is video scanned to produce image data which is digitized in accordance with the teachings of the invention to produce a non-minutiae digitized numerical identifier indicative of the digit print image, and this digitized numerical identifier is compared with a numerical identifier read from an identification card means identifying the person to be identified, to verify the identity of that person.

Various other objects and advantages of the invention methods and system will be apparent from that set forth hereinafter, and some of the specific objectives of the invention are recited hereinbelow.

OBJECTS OF THE INVENTION It is an object of the invention to provide a biometric means for comparing the fingerprint of an individual whereby a rapid and highly fraud-proof check may be made.

It is another object of the invention to make the fingerprint image expediently available for immediate analysis to render approval or disapproval of the identity of a given person from whom the fingerprint is taken.

It is a general objective of the invention to provide a system and related methods by which an individual fingerprint may be video-scanned and digitized in such a manner that the procedure produces a numeric identifier uniquely related to the pattern of the fingerprint, this identifier consisting of a specified number of digits or bytes to identify the fingerprint against an actual fingerprint of an individual at the time positive identification is required. It is a specific object of the invention to provide a non-minutiae digitized numerical identifier having less than 400 bytes of fingerprint identification data, and in particular, a verifiable identifier having less than 100 bytes of fingerprint identification data for application to mag-stripe personnel identification cards, as exemplified by the provision disclosed herein of a non- minutiae digitized numerical identifier having 24 bytes of fingerprint identification data.

It is yet another object of the invention to provide means by which a fingerprint image format may be positioned automatically in relation to the video scanning means, in such a way that the position is predetermined and will be reestablished each time that a print format means is placed before the video scanner, thus insuring that a subsequent scanning operation will always produce consistent and reliable field of scan results.

It is still another object of the invention to provide means and methods for selectively analyzing a plurality of different fingerprint pattern parts of the stored fingerprint image data and computing a ridge count for each of the plurality of fingerprint pattern parts, and then compiling a data matrix comprised of a plurality of ridge counts computed for the plurality of fingerprint pattern parts to provide a non-minutiae digitized numerical identifier indicative of the image of a fingerprint of a person to be identified.

It is still another object of the invention to provide a predetermined sequence of selectively analyzing a plurality of different fingerprint pattern parts of the stored fingerprint image data, which fingerprint pattern parts exist within a fingerprint identity window defined by the invention.

It is yet still another object of the invention to provide a non-minutiae digitized numerical identifier indicative of an image, of a fingerprint of a person to be identified, which is recordable within the magnetic stripe of a credit card personal to the person and therefore, the present invention facilitates the use of a credit card as a verifiable identification card for entitling the user to certain services such as charged purchases and check cashing.

It is even a further object of the invention to provide a fingerprint identification system and inventive methods utilized therein, which can be completely software controlled and automated to eliminate the possibility of human error, to increase the reliability of the identification being made and to eliminate any constant supervision as usually required with conventional identification procedures. The invention, by utilizing an unchanging characteristic of an individual for making an identification, is not subject to obsolescence and at the same time may be constructed at various levels of sophistication depending on the degree of security of reliability which is desired. The system can be made an integral part of other systems in which information about individuals is taken and recorded and the system can be so constructed with controls that provide for immediate revocation of the privileges of benefits given any individual identified in the system.

It is also another object of the invention to provide a method for the automatic non-minutiae identification of a fingerprint of a person to be identified which includes a method for determining the location of the fingerprint image data stored in a memory means with the whitespace data produced by scanning an image of a fingerprint, and to define a fingerprint or digitprint identity window so as to define a predetermined "area of analysis", which area is defined depending on the specific needs of the end-user application, and with respect to a predetermined "window-size", to enable defining the dimensional area of the fingerprint identity window. The foregoing and other objects, features and advantages of the invention will be apparent from the following more detailed description of preferred embodiments and methods of the invention, as illustrated in the accompanying drawings.

DEFINITIONS

It is well known that fingerprints contain specific features, called minutiae, which are unique and allow identification of people by their fingerprints or even a toe print. By definition, a minutiae is either: (1) a bifurcation, which is the location where a given line forks into different lines; or (2) a ridge ending. Minutiae are usually recorded with three coordinates: two coordinates "x" and "y" for the position of the minutiae relative to a coordinate system: and one coordinate "a", which is an angle representing the average direction of the lines around the minutiae point.

In contrast, the present invention methods and system are "non-minutiae" based and either provide or utilize a non-minutiae digitized numerical identifier which is uniquely related to the pattern of a fingerprint it identifies. The non-minutiae digitized numerical identifier is provided by selectively analyzing different parts of a fingerprint and deriving from each part a byte numeric which is directly related to the ridge count computed for that part. This non-minutiae digitized numerical identifier can also be described as a "verification string".

The term "digitizing" is used herein to refer to the process by which the non-minutiae digitized numerical identifier is derived by the respective invention methods disclosed herewith; and, the term "digitized" is used herein to identify the non-minutiae numerical identifier derived by such process.

The "ridge counts" are computed by analyzing or examining selected horizontal and vertical and diagonal memory data lines of the fingerprint identity window defined by the present invention, and counting the number of greylevel shifts from "white" (greylevels 13, 14 or 15) to "black" (greylevels 0 through 12) .

The video digitizer of the system invention is the means employed for converting the video scanned fingerprint image data (FID) and whitespace data into digital data to generate within its memory a digitalized picture of that scanned by the video scanner, i.e. the inkless format providing an image of a fingerprint of a person to be identified; but, it is the software-controlled processor means of the invention which functions to selectively analyze the digital data to provide a digitized numerical identifier indicative of the fingerprint image. The present invention discloses an inventive method step termed "image framing" wherein, prior to selectively analyzing different parts of the fingerprint image data and prior to defining a fingerprint identity window, the fingerprint image and whitespace digital data stored in an addressable memory means (RAM) , located in the video digitizer, are framed to a predetermined dimension, and the location of the fingerprint image data stored in this memory means with whitespace data is determined by determining: (1) X-START and X-END values to indicate the start and the end of the fingerprint image data along the X-axis, and (2) Y-START and Y-END values to indicate the start and end of the fingerprint image data along the Y- axis. The "image framing" invention method also includes an "image frame sizing" step which essentially frames the digital fingerprint and whitespace image data contained in memory.

The "fingerprint identity window" defined by the present invention is the "area of analysis" defined within the fingerprint image data stored in memory. It is this fingerprint identity window which is selectively scanned and analyzed in accordance with the teachings of the present invention, to provide a non-minutiae digitized numerical identifier indicative of the fingerprint image data of a fingerprint of a person to be identified. The "fingerprint identity window" is defined depending on the specific needs of the end-user application, and is set by determining a "window-size". The purpose of the "verification string" is to provide a tailorable degree of certainty into the comparison of encoded data on i.e., the magnetic stripe of a credit card, or other article presented by an individual used as a personal identification means, and the individual's fingerprint image.

This "verification string" can be variable in size, depending on multiple factors. The invention affords the provision of a verification string (or digitized numerical identifier) which has less than 400 bytes of fingerprint identification data, or one having less than 100 bytes of FID as applicable to a magnetic stripe credit card or a smart card or other personal identification card means, or, in particular, an identifier having only 24 bytes of FID which as disclosed in a preferred method and embodiment of the present invention is uniquely applicable to the magnetic stripe of a credit card.

An "element" is a calculated value, generated by the end-user application.

A first factor is the size of the "window" in which image analysis is performed. The larger the window, the more verification data can be generated for comparison purposes. Since the "window" is variable depending on end- user applications, the size of the verification string can vary as well. Thus, it is reasonable to say that increasing the "window-size" used in verification string generation presents the opportunity to increase the number of elements which comprise the verification string.

A second factor is the formulas or calculations used to generate or calculate the verification string. The calculations performed to generate the verification string can vary from one end-user application to another. Any mathematical formula or statistical computation based on ridge counts, whether individually or as a sum, can be used as an element in the verification string data matrix which is compiled.

Both of the above scenarios address the flexibility of the verification string size in designing end-user applications with varied degrees of verification confidence. Of course, different applications might have the same number of verification string elements, yet comprise of entirely different formulas used to generate that data. In other words, two end-user applications may comprise verification strings having a different total number of elements, and the applications may generate each element of its verification string differently.

Lastly, the positioning of each element within the verification string could be different from one application to another. For instance, one application might use Yc (Y Center Line Count) as a value for the seventh element of the verification string, as disclosed herein, and yet another application may use the same value in another element of its verification string.

DETAILED DESCRIPTION OF INVENTION METHODS

A preferred form of the present invention system and methods combinatively utilize an inkless media for the purpose of taking or providing an image of a fingerprint or digitprint. An image of such print is produced by placing a digit of the person to be identified within a 2" x 2" framed format 1 as shown in FIG. 1A, which contains a treated material which when touched by a finger, utilizing an inkless process, causes immediate development of an image of a fingerprint of such finger in a black and white appearance, to provide a good quality scannable image of a fingerprint. The use of this inkless means for taking a fingerprint of a person to be identified overcomes the disadvantages of conventional fingerprint taking techniques. Of course, it is within the scope of the present invention to be applicable to video scan a fingerprint image imprinted upon other media, or by other methods.

After the fingerprint has been taken, the inkless framed format 1 is placed within a format holder 3 which is mounted on the face plate of the system housing. The placement of the inkless framed format within the format holder 3 is illustrated in FIG. IB.

FIG. 2 shows the predetermined position orientation of a video scanning camera 4 and a 16 mm lens 5 associated therewith, to the center of the inkless framed format when it is positioned within the format holder. The center 6 is the center of the inkless media 2 bearing the fingerprint image. A preferred predetermined distance of 2 1/2 inches is set between the center 6 and the face of lens 5.

Accordingly, this provides means by which a fingerprint may be positioned automatically in relation to a video scanning system, in such a way that the position is unique and will be reestablished each time that the framed format 1 is placed within the format holder and thus within the field of scan of the video scanner, to insure that any subsequent scanning operation will always produce proper and desirable results. The use of the inkless fingerprint media for taking the person's fingerprint without requiring the direct application of ink to the person's finger, and under controlled conditions, affords that the person's print may be repeatedly produced with the same clarity and detail, thus facilitating an accurate comparison between prints.

After the fingerprint has been taken on the inkless means of the framed format, the framed format 1 is placed within the holder 3 with the fingerprint image facing the housing face plate and towards the field of view of the video scanner. It is to be noted that in an effort to diminish background reflection of light from the framed format 1, the framed portion has been blackened, as shown in, for example, FIG. 7A.

As shown in the FIG. 6A flow chart, in operation, after the fingerprint format is placed in the format holder and an identification card means is placed in a card reader, system command sequences are issued to the video scanner and the digitizer to commence and complete the scanning and digitizer functions.

Thus, the image of a fingerprint is video scanned to produce image data which is provided to a digitizer which converts the image data into digital image data which is stored in an addressable memory means (RAM) of the digitizer. To accomplish this, a sequence of commands are issued to the digitizer's "command port". This command sequence is specific to each end-user application. After these commands are issued, the digital fingerprint image and whitespace data generated by the scanning procedure and contained in memory in the digitizer, is ready for analysis.

Firmware Process Overview - The controlling firmware of the invention system has several components, each of which perform a specific task which, when combined, provide a series of processes that will take a fingerprint sample and verify it against verification data to insure the authenticity of the provider of the sample. These processes include the following routines:

Comparison Data Retrieval Routine Image Capture Routine

Image Sizing Routine

Algorithm Data Generation Routine

Verification Data Generation Routine

Data Confirmation Routine

Each of these routines are executed in sequence, and will be discussed in order. However, before the firmware verification process can commence, that set forth hereinabove must have been performed.

Comparison Data Retrieval Routine - This routine controls receipt of the Provider's verification data recorded on the identification card means, which is compared against data computed from the fingerprint sample to approve or fail the Provider's authenticity. The verification data could be encrypted and this will be discussed in a following disclosure section, along with an associated decryption function. The verification data (also termed "non-minutiae numerical identifier") recorded within the identification card means is read and stored in a 12 element array which is located in the processor of the invention system. This matrix has the same layout as the Generated Data Matrix which will be discussed subsequent to the following.

Image Frame Sizing Routine - This routine is generated subsequent to the Image Capture Routine which controls the operation of the video camera and the digitizer to capture the fingerprint image and whitespace data in memory. With reference to FIGS. 7A and 7B, this is accomplished as follows:

Note: "Whitespace" is defined as a greylevel equal to 13, 14, or 15. a) Memory frame locations (128,Y), where 0 < Y < 255 are inspected, when three consecutive rows of whitespace are found, Y-TOP is defined as the current Y- value; and b) Memory frame locations (128,Y), where 255 > Y > 0 are inspected, when three consecutive rows of whitespace are found, Y-BOTTOM is defined as the current Y- value. c) With respect to FIGS. 8A and 8B, once Y-TOP and Y-BOTTOM values are established, the X-Axis Range of the fingerprint image data needs to be computed. This is accomplished by scanning (i.e., examining) each column (vertical line) to find three consecutive columns of whitespace. Once three columns are found, the next column containing a greylevel other than whitespace (i.e., black) is considered to be part of the Image. Two X-Axis values, X-START and X-END, need to be set, to indicate the start and end memory data locations of the Image on the X-Axis, respectively. X-START is determined by scanning Frame Locations (X,Y), where 0 < X < 255 and Y-TOP < Y < Y-BOTTOM. This value indicates where the Image "starts" on the X-Axis. X-END is determined the same way, only reversing the X-Axis scan direction from 255 > X > 0, to determine where the Image "Ends" on the X-axis, d) With respect to FIGS. 9A and 9B, now that the X-Axis range has been computed, the Y-Axis range of the FID needs to be computed. This is accomplished in a method similar to that used for the X-Axis Range.

Each row (horizontal line) is scanned, and, syncing on three consecutive whitespace rows, the next row that contains a greylevel other than whitespace is considered to be part of the image.

Two Y-Axis values, Y-START and Y-END, need to be set, to indicate the start and end memory data locations of the Image on the Y-Axis, respectively. Y-START is determined by scanning Frame Locations (X,Y) , where X-START < X < X-END and Y-TOP < Y < Y-BOTTOM. Y-END is determined in similar fashion, only different being that the direction of scan along the Y-Axis is from Y-BOTTOM > Y > Y-TOP. e) With respect to FIGS. 10A and 10B, all values generated must be validated to insure that an accurate image has been scanned and sized. If any of the following conditions fail, a "Poor Image Quality" error is generated, and the system recycles.

The conditions which will cause this error are: i. Y-BOTTOM < Y-TOP ii. X-END < X-START iii. Y-END < Y-START If any of the above conditions are true, then the fingerprint sample provided to the Digitizer should be discarded and a new sample taken.

If none of the above error conditions exist, then the fingerprint sample is considered to have been accurately scanned and sized. The area within the memory frame where the fingerprint image data exists can be illustrated as shown in FIG. 10B.

Fingerprint Identity Window "Area of Analysis"

Prior to calling the mainline routine for the algorithm data generation routine (ADGR) , locations must be set to describe the "window" within the fingerprint image data, stored in the memory frame, which is going to be analyzed. This "window" is a box, determined around an origin point defined as (XC,YC) . XC and YC, or more appropriately called X-Center Line and Y-Center Line, are determined from values generated in the Image Sizing Routine, according to the following formulas:

XC = X-END - (X-END - X-START) / 3 YC « Y-END - (Y-END - Y-START) / 2 The difference between the two calculations is based upon the knowledge that the lower portion of a person's fingerprint (i.e., the portion containing the whirl) will be located closer to X-END than X-START. Thus, the XC value should start in the rightmost third of the print (hence, the division by 3) as that is where the whirl is likely to exist in the digitalized image. YC is simply determined to be the standard Center Line between the two Y points on the frame's Y-Axis. Thus, assuming a print has been sized to exist from (50,50) to (200,150), (XC,YC) would be defined as (150,100). Once (XC,YC) has been established, the "area of analysis" can easily be defined to the ADGR mainline routine. This area is defined depending on the specific needs of the end-user application, and is set by determining a "window-size". The "window-size" is always an odd number. The

"area of analysis" is then defined as XC ± DIFF and YC ± DIFF. DIFF is computed with the following formula:

DIFF = h (window-size - 1) So, if the "window-size" is 73, the "area of analysis" would be appropriately defined as (XC ± 36, YC ±

36), or, in our example above, from (114,64) to (186,136).

Accordingly, the dimensional area of the fingerprint identity window is defined by predetermining a window-size for the fingerprint identity window and defining its dimensional area as from (XC - DIFF, YC - DIFF) to (XC + DIFF, YC + DIFF) where DIFF - h (window-size minus 1), wherein (XC - DIFF) = Xs, (YC - DIFF) « Ys, (XC + DIFF) = Xe, and (YC + DIFF) = Ye.

In addition to the X and Y Center Line values, there are four other variables which are used in Algorithm computations and these values are set forth hereinbelow and have been recited in connection with determining the dimensional area of the fingerprint identity window:

Description: Symbol: Value:

Window X-Axis Start Xs XC - DIFF

Window X-Axis End Xe XC + DIFF

Window Y-Axis Start Ys YC - DIFF

Window Y-Axis End Ye YC + DIFF

Once the proper values have been set, the "area of analysis" can be illustrated as shown in FIGS. 11A and 11B. Algorithm Data Generation Routine - The Algorithm

Data Generation Routine (ADGR) consists of a series of modules designed to generate 16 ridge-count values to be used in the computation of the Generated Data Matrix. The processing for each of these values will be discussed after the following presentation:

Ridge counts are generated by examining the horizontal and vertical lines set forth hereinbelow, and counting the number of greylevel shifts from "white"

(greylevels 13, 14, or 15) to "black" (greylevels 0 through

12) .

The computation of the counts for the values of the Algorithm Output Data will now be described.

Value #1: SI ; Diagonal \ Absolute Count (FIG. 12) This routine generates a count of ridges contained on the diagonal line drawn from point (Xs,Ys) to

(Xe,Ye) . Since the "window" is an absolute square, this relationship is a one-for-one increment along the X-Axis and Y-Axis, starting at Xs, and ending at Xe.

Value #2: S2 ; Diagonal / Absolute Count (FIG. 13)

This routine generates a count of ridges contained on the diagonal line drawn from point (Xs,Ye) to (Xe,Ys) . Since the "window" is an absolute square, this relationship is a one-for-one increment along the Y-Axis for each decrement along the X-Axis, starting at Xs, and ending at Xe. Value #3: Yam ; Y-Axis A-Range Maximum Absolute Count (FIG. 14)

This routine yields the highest number of ridges found on a horizontal line in the Y-Axis "A-Range". The Y- Axis "A-Range" is defined as: Ys ≤ horizontal line < YC.

In the example of FIG. 14, of the horizontal lines counted, the value of "Yam" would be set to "25", assuming that no other horizontal line contained a ridge count greater than 25. The "A-Range" is indicated with single-line borders.

Value #4: Ybm ; Y-Axis B-Range Maximum Absolute Count (FIG. 15)

This routine yields the number of highest number of ridges found on a horizontal line in the Y-Axis "B- Range". The Y-Axis "B-Range" is defined as: YC < horizontal line < Ye.

In the example of FIG. 15, of the horizontal lines counted, the value of "Ybm" would be set to "11", assuming that no other horizontal line contained a ridge count greater than 11. The "B-Range" is indicated with single-line borders.

Values #5 & 6: Ya ; Y-Axis A-Range Average Count (FIG.

16)

This routine yields the total number or ridges found on horizontal lines in the Y-Axis "A-Range". For computation purposes, this "overall total" is stored as two numbers, Yaα and Yaβ. Yaα is the total number of 256 ridges in the "overall total" (i.e.: if Yaα is "2", then there are at least 512 ridges in the "overall total") . Yaβ is the remaining number of ridges counted (i.e.: 6) which is always a number under 256. The Y-Axis "A-Range" is defined as: Ys < horizontal line < YC. In the example of FIG. 16, if the horizontal lines summed to 516, the value of "Yaα" would be set to "2", and the value of "Yaβ" would be set to "4". The "A- Range" is indicated with single-line borders.

Values #7 & 8: Yb ; Y-Axis B-Range Average Count (FIG.17)

With reference to the Generated Data Matrix, the Verification Data Generation Routine will now be presented.

This routine takes the output of the Algorithm

Data Generation Routine and creates the "Generated Data

Matrix". For a full understanding of this process, refer to the two tables: "Algorithm Output Data" and "Generated Data Matrix", presented above.

The first element in the GDM (Generated Data Matrix) is equal to the value of the first number in the AOD (Algorithm Output Data) . This element is known as "SI", or the "Diagonal \ Absolute Count". The second element in the GDM is equal to the value of the second number in the AOD. This element is known as "S2", or the "Diagonal / Absolute Count".

The third element in the GDM is equal to the value of the third number in the AOD. This element is known as "Yam", or the "Y-Axis A-Range Maximum Absolute Count".

The fourth element in the GDM is equal to the value of the fourth number in the AOD. This element is known as "Ybm", or the "Y-Axis B-Range Maximum Absolute Count". The fifth element in the GDM is a calculated value using the fifth and sixth numbers in the AOD. The calculated value can be indicated as follows:

value = (fifth * 256 + sixth) ÷ (window-size ÷ 2)

In other words, the computation is equal to the fifth number in the AOD multiplied by 256, plus the sixth number in the AOD. The result is then divided by _ the window size to give the calculated value. This element is known as "Ya", or the "Y-Axis A-Range Average Count". The sixth element in the GDM is a calculated value using the seventh and eighth numbers in the AOD. The calculated value can be indicated as follows:

value = (seventh * 256 + eighth) ÷ (window-size

+ 2)

In other words, the computation is equal to the seventh number in the AOD multiplied by 256, plus the eighth number in the AOD. The result is then divided by h the window size to give the calculated value. This element is known as "Yb", or the "Y-Axis B-Range Average Count". The seventh element in the GDM is equal to the value of the ninth number in the AOD. This element is known as "Yc", or the "Y-Axis Center Line Absolute Count".

The eighth element in the GDM is equal to the value of the tenth number in the AOD. This element is known as "Xam", or the "X-Axis A-Range Maximum Absolute Count".

The ninth element in the GDM is equal to the value of the eleventh number in the AOD. This element is known as "Xbm", or the "X-Axis B-Range Maximum Absolute Count".

The tenth element in the GDM is a calculated value using the twelfth and thirteenth numbers in the AOD. The calculated value can be indicated as follows: value = (twelfth * 256 + thirteenth) ÷ (window-size ÷ 2)

In other words, the computation is equal to the twelfth number in the AOD multiplied by 256, plus the thirteenth number in the AOD. The result is then divided by h the window size to give the calculated value. This element is known as "Xa", or the "X-Axis A-Range Average Count".

The eleventh element in the GDM is a calculated value using the fourteenth and fifteenth numbers in the AOD. The calculated value can be indicated as follows:

value = (fourteenth * 256 + fifteenth) ÷ (window-size

+ 2)

In other words, the computation is equal to the fourteenth number in the AOD multiplied by 256, plus the fifteenth number in the AOD. The result is then divided by h the window size to give the calculated value. This element is known as "Xb", or the "X-Axis B-Range Average Count". The twelfth element in the GDM is equal to the value of the sixteenth number in the AOD. This element is known as "Xc", or the "X-Axis Center Line Absolute Count".

Fingerprint Identification System Data Confirmation Routine This routine is responsible for comparing the Comparison Data Matrix (CDM) against the Generated Data Matrix (GDM,) and determining if the fingerprint sample given by the Provider mathematically matches the verification data on the Provider's portable personnel identification means. Each element of the CDM is compared against its counterpart in the GDM. That is, the first element of the CDM is compared against the first element of the GDM, the second element of the CDM is compared against the second element in the GDM, and so on.

The absolute difference between elements is limited to specific pre-defined "tolerances". These tolerances will vary from application to application, depending on the needs of the end-user. An end-user who wants very strict regulation would have lower tolerances than an end-user who wants average regulation. In other words, one end-user may want ±3 tolerance whereas another might want ±1 tolerance.

As an example, the first through seventh elements will always have one level of tolerance higher than the eighth through twelfth elements. In other words, if the eighth through twelfth elements are measured with a ±2 tolerance, then the first through seventh elements will have a tolerance of ±3.

To determine whether or not a fingerprint sample is approved, a "confidence level" has to be achieved. This confidence level starts at zero. When each CDM/GDM element is compared, and the difference falls within the acceptable tolerance, then the confidence level is increased by 8.33%.

The actual confidence level that must be achieved in order for a fingerprint to be "approved" is again determined by the specific application. One end-user might want a higher confidence level than another end-user.

After all elements have been compared, and the confidence level is determined, a flag is set to indicate whether or not the sample has "passed" the confirmation process. The entire process (2 - Image Capture through 6 -

Data Confirmation) is repeated up to 10 times.

If a sample is confirmed two consecutive times, then the fingerprint sample is "approved", an appropriate confirmation message is generated for the Obtainer to view, and the device recycles.

If a sample is rejected two consecutive times, then the fingerprint sample is "failed", an appropriate rejection message is generated for the Obtainer to view, and the device recycles.

If in the ten process cycles the firmware cannot obtain two consecutive "passes" or "failures", then the fingerprint sample is "unable to verify", an appropriate message is generated for the Obtainer to view, and the device recycles.

It should be apparent to any person skilled in the art to which this invention pertains that the disclosure set forth hereinabove with respect to the calculation of the plurality of counts, with reference to either a diagonal line or a horizontal line or a vertical line, pertains to a line of memory data contained within the fingerprint identity window area being analyzed. The foregoing has been disclosed with respect to a preferred method and system wherein the Generated Data Matrix provides 24 bytes of fingerprint identification data, each element of the GDM containing 2 bytes of verification data. The 24 byte non-minutiae digitized numerical identifier is recordable within the confines of a portable personnel identification means and in particular, the magnetic stripe of a credit card to allow the credit card to be used as an identification card for entitling the user to certain services, as for example, charged purchases and check cashing. This digitized numerical identifier can also be stored in a memory means included in a smart card.

As to the particular application of the invention system and methods for providing a 24 byte non-minutiae digitized numerical identifier which is recordable within the magnetic stripe of a credit card to allow the credit card to be used as a portable personnel identification card, regulations of the American National Standards for financial services, financial transaction cards magnetic stripe encoding, limit the magnetic stripe and coding as follows:

TRACK 1 maximum of 79 alphanumeric characters TRACK 2 maximum of 40 characters, numeric only TRACK 3 maximum of 107 alphanumeric characters

VARIABLE RESOLUTION The foregoing presentation of the invention methods for image sizing, image framing, and that set forth with respect to defining a fingerprint identity window, bear reference to a resolution area base 256. It should be apparent that the present invention is not limited to this exemplary resolution area since it is well within the teachings and scope of the present invention to employ a resolution area base 512. Accordingly, it will be apparent to those skilled in the art in light of the foregoing disclosure that the invention should not be limited to a resolution area base 256. ENCRYPTION/DECRYPTION

Verification String encryption routines can take a myriad of forms. Each scheme is application dependent, meaning that a scheme used for one application will not be used in a similar application - thus reducing the possibility of fraud. Since the scheme for each application is different, and bound in the verification firmware EPROMS, the possibility of unauthorized card duplication is reduced, as duplicated cards for one application would not yield valid verification data in another application. Two exemplary encryption schemes are as follows:

Scheme 1: Digit Reversal Scheme This "encryption scheme" takes each of the twelve numbers in the Verification String and reverses the digits. In other words, if the Verification String contains the following numbers:

01 40 36 24 22 05 10 18 14 21 04C then the "encrypted" data would appear as follows: 10 04 63 42 22 50 01 81 41 12 400

To "decrypt" the data in an application program, the programmer need only reverse the digits back to obtain the original numbers.

Scheme 2: Digit Complement Scheme This "encryption scheme" operates on all 24 digits of the Verification String as a whole, treating each digit as a separate entity. Each digit is subtracted from nine (9) to achieve a "complement" value. For instance:

01 40 36 24 22 05 10 18 14 21 04B would appear as follows once encrypted:

98 59 63 75 77 94 89 81 85 78 959

This complement scheme has the same affect as taking each of the twelve numbers and subtracting each number from ninety-nine (99) to achieve the "encrypted" value. To reverse the process, the user only need to subtract 9 from each of the 24 encrypted digits to achieve the original number (ignoring the negative sign) .

As stated above, data encryption will vary from application to application, to avoid multiple applications from having similar verification data, and thus introducing potential misuse of the encrypted verification data. The encryption method is decided in advance, and appropriate decryption logic is programmed into the Comparison Data Retrieval Routine, such that the decrypter logic and means of implementation are contained in the BCC52 processor of the system invention.

As to the implementation of the encryption scheme aspect of the present invention, in addition to providing a fingerprint sample, the Provider also presents identification card means (i.e., identification card with a magnetic stripe) which contains his or her encrypted verification data (i.e., encrypted digitized numerical identifier) , the identification card is then placed in the card reader for retrieval and decryption of the "comparison data".

Upon decryption, the "comparison data" is stored in a 12 element array, known as the "Comparison Data Matrix", which has the same layout as the "Generated Data Matrix" presented hereinbefore.

If any errors are encountered during this retrieval process, then an appropriate error message is generated and the system recycles. Such error messages are specific to the individual application (i.e., a system with a magnetic stripe card reader would have a "Card Reader Error" or a "Channel Read Error" error message) . Furthermore, the encrypted identifier could also be included on a check payable within a check cashing identity verification application of the present invention. As set forth in the appended claims, the present invention is applicable to: recording an encrypted or non- encrypted non-minutiae digitized numerical identifier within the confines of a portable personnel identification means, personal to a person, such as a credit card or a smart card, identity verification of a person to be identified with or without an encryption scheme, and payable check verification of identity of payee, with or without encryption.

As to the recording application, two services could be performed: (1) direct or indirect personal contact with the persons to be identified, deriving non-minutiae digitized numerical identifiers indicative of the fingerprints of such persons, and recording the non- minutiae digitized numerical identifiers within identification means, personal to such persons; or (2) performing such a service but providing the derived non- minutiae digitized numerical identifiers to another party for the performance of the recording procedure.

As to the Identity Verification Application of the present invention, this could be accomplished with direct or indirect personal contact with persons to be identified.

With regard to the payable check verification of identity of a check payee, the check payable could include a numerical identifier to be verified with a digitized numerical identifier indicative of a fingerprint of a check payee named on the check payable, or preferably no numeric identifier would be included on the check payable and verification of the identity of the person submitting the check payable in a check cashing application would be accomplished by verification of comparison of a non- minutiae digitized numerical identifier indicative of a fingerprint of a person submitting the check for cashing, with the numerical identifier contained within a portable personnel identification means submitted by such person for identification as the check payee of the check payable. With reference back to the identification verification application of the present invention, where • verification of identity is accomplished by comparing the numerical identifier of identification means with the non- minutiae digitized numerical identifier derived from a fingerprint of such person to be identified, upon finding non-verification, the portable personnel identification means would be withheld by the invention system, or in the case where a smart card is presented as the identification means, the functional integrity of such smart card could be destroyed by known techniques and devices incorporated into the system invention. Thus, it is apparent that there has been provided, in accordance with the invention, an identification system that fully satisfies the objectives, aims and advantages set forth above. While the invention methods have been described in conjunction with specific applications thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications and variations which fall within the spirit and scope of the appended method claims.

The terms and expressions which have been employed in the foregoing specification are used therein as terms of description and not solely of limitation, and there is no intention, in the use of such terms and expressions, of excluding equivalents of the features shown and described or portions thereof, it being recognized that the scope of the invention is defined and limited only by the appended method claims.

FINGERPRINT IDENTIFICATION SYSTEM INVENTION A description of the system invention will now be presented with reference to FIGS. 24 - 32 which are illustrative of the system invention, and FIGS. 4 - 6B and FIGS. 33 and 34 which provide flow charts which are descriptive of the operation control of the system invention. FIG. 24 is a block diagram of the invention system which shows the basic interconnection of the system components including the video camera 4, and the accessories LCD display 40, printer means 50, and PPI/MS Reader 60. An illustrative power supply means PS for providing appropriate voltage supply to the system components is also shown.

The system invention can be embodied in three specific configurations which differ from each other as to the application of the system invention and the components utilized for a respective application. Each of the three embodiments incorporate the following: an inkless framed format holder means 3, video scanning means 4, lens 5, digitizer 10, processor 20, LCD driver means 30, a four- slot motherboard bus connector Z8, and a portable personnel identification card reader means 60.

Prior to presenting a description for each embodiment of the system invention, the basic system as depicted in FIG. 24 will now be described. Video scanner 4 scans an inkless format means providing an image of a fingerprint of a person to be identified, after this fingerprint image format 1 is placed within the inkless format holder means 3 which automatically positions the format 1 in relation to the video scanner 4 in such a way that the position is predetermined and will be reestablished each time that a print format means is placed before the video scanner, thus insuring that a subsequent scanning operation will always produce consistent and reliable field of scan results. As shown in FIG. 24, the video output of scanner

4 is connected to digitizer 10 via a shielded coaxial cable 9. The video scanner 4 receives power from the 120 volts AC supply, and a ground is provided via line 7 from pin 2 of Z8. In operation, the video scanner scans the image of a fingerprint provided on an inkless means 2 to produce fingerprint image data and whitespace data which is outputed to the video digitizer board 10. The primary function of the video digitizer board 10 is to convert the fingerprint image and whitespace data signals from the video scanner into digital image data i.e., numerical data, which digital image data is stored in an addressable memory means, RAM, included in the digitizer 10. Thus, the stored digital image data is then available to the system program-controlled processor 20 for evaluation of the scanned image data information.

The scanned image data information contained in the video camera output signal is made up of discrete points of picture elements, commonly called pixels. Each pixel varies in brightness, depending on the image scanned, through a range of "grey levels" from black to white. In digitizer 10, these grey levels are separated into 16 numerical values from 0 (black) to 15 (white) . Each horizontal line of the image data being viewed contains 256 pixels and the circuitry of the digitizer samples 256 lines. This results in 65,536 pixels or discrete numerical values that the digitizer must store in its random access memory means. Since the pixels are supplied in a scanning sequence (from left to right in the viewed image) it is necessary that the sampling in some subsequent storage of the pixel values be synchronized with camera scanning sequence. Signals are provided, along with the fingerprint image and whitespace data outputed from the camera. These combined signals, image and sync, are commonly referred to as "composite video".

Circuit means of the digitizer functions to extract both horizontal (line) and vertical (frame) synchronization signals. Other circuitry of the digitizer 10 allows the system microprocessor 20 to control a variety of functions under software control. The primary function of the digitizer 10, as referred to earlier, is to convert the scanned image data into numerical values for later evaluation by the software controlled processor. The operation of the digitizer 10 of the invention is well known to those skilled in the art and a specific designation of a digitizer utilized in the system invention is presented hereinafter along with designations for the other components incorporated into the present system.

The program-controlled processor means 20 selectively analyzes a plurality of different fingerprint pattern parts of the digital image data contained in the digitizer, and the processor includes means for accomplishing the inventive methods set forth in the foregoing, such as means for computing a ridge count for each of the plurality of selectively analyzed different fingerprint pattern parts, means for compiling a data matrix comprised of ridge counts computed for these different fingerprint pattern parts, means to provide a non-minutiae digitized numerical identifier indicative of the image of the fingerprint of a person to be identified, and means for comparing the numerical identifier provided by the card reader 60 with the non-minutiae digitized numerical identifier, to verify the identity of a person to be identified. Reference to the foregoing description will also provide information as to the other inventive methods of the invention such as that set forth for Image Capture, Image Sizing and the defining of a fingerprint identity window.

The flow charts illustrated in FIGS. 4 - 6B, 33 and 34 provide the system operations performed by the processor means 20 under software control.

The LCD Driver means 30 communicates with the processor 20 via J4 and Z8, and its output is connected to LCD display means 40 via connector J6. Printer 50 is connected to processor 20 via connector J5.

A portable personnel identification means magnetic-stripe reader 60 is connected to processor 20 via RS-232-C, 25 pin serial connector 8 and connector Jl. This reader is provided with a simple reset circuit (not shown) to initialize the control microprocessor when power is first supplied to the system. Appendix A attached hereto describes the software utilized in the system of the invention.

The disclosure set forth hereinabove and attached hereto, with reference to the drawings, will enable any person skilled in the art to which this invention pertains, to assemble and operate the system invention in accordance with the inventive methods provided herein.

The specific circuitry incorporated in the particular embodiment of an automatic fingerprint identification system constructed in accordance with the present invention and described with reference to the respective drawings, can be constructed from discrete elements more advantageously as from integrated circuits.
