Abstract
This invention relates to a document authentication concept wherein a transparent tape having encoded text thereon is applied to the document. The encoded text printed on the transparent tape is printed with invisible ink so that the message thereon is not visible to the unaided eye. Preferably, the ink is visible in the infrared range. With such a combination, the authentication medium can be applied to a document that has a predetermined format so that the tape can be placed over a portion of the text and the latter will still be readable.

CA 021234~6 1998-03-11 Summary of the Invention A scheme has been devised whereby government issued documents can have encrypted or encoded data thereon without interfering with the format of the document. The encoded or encrypted data is printed on a transparent tape with invisible ink. The ink becomes visible when exposed to either ultra violet light or infra-red light depending upon the dyes in the invisible ink. In preparing the label, the data on the document is scanned by a reader (scanner), and the information derived therefrom is encoded. A
code is then devised to be printed upon the transparent label, and is done so vvith invisible ink. The transparent label is then applied to the document and because of the use of the invisible ink, one can read the text covered by the transparent tape.
When one wishes to determine the authenticity of the document, that person is provided with a device that will direct light of appropriate wavelength onto the label so that the ink becomes visible. The device will also have a decoding capability so that the operator can determine if the government document is genuine and the holder of the document is the person to whom the document was issued.
Other aspects of this invention are as follows:
A document having provision for determining authentication thereof, com prising:
a) a sheet having human visual text printed thereon, b) a transparent label attached to the sheet, and c) text printed upon the transparent label with invisible ink.
A document having provision for determining authentication thereof, comprising:
a) a plurality of sheets laminated to one another, b) one of said sheets having human visual text printed thereon, c) a second of said sheets being transparent and attached to the first sheet, and d) text printed upon said transparent sheet with invisible ink.

license, but it will be appreciated that the principles of the invention can be applied to other types of documents, whether the same are governmental or industrial issued documents, so long as the document~ are for the purpose of identifying a right or privilege to which the issuer thereof i5 entitled.
With reference initially to FIG 1, a do_ - ~ 10 in the ~orm of a driver's license is ~hown having a photograph 12 of the per60n to whom the license was i85~ed. The document 10 can be made of a single layer, or ~heet, or a plurality of layers that are laminated together. A document composed of a single layer or multiple layerci in this specification, including the claims, will be referred to collectively as a sheet. The driver~s license also contains other data such as the state in which the l~cense has been issued 13, the operator number 14, the expiration date 16, the license type 18, the birth date of the recipient 20, the gender 22 of the recipient, the name of t~e recipient 26, the address of the recipient 28 and i~suer's identification data 30. It will be noted that the driver'~ licen~e ha~ a dense data field for the items that were ~UBt referenced.
As such, it would be difficult to place additional information on the face thereof, as ~t i~ necessAry that the document 10 be of convenient size. As a concequence, it i~
within the contemplation of thi~ invention to provide a transparent label 34 havinq ~ro~ data 36 printed thereon, as shown in FIG 2 that will have correspon~e~ce to the data printed on the ~o~ 10. ~he en~o~ed data 36 can include encrypted data, a bar code, or ~ny other col,venient format.
As shown, the ~nco~e~ ~ssage 36 i~ in the form of alpha-numerics. The label 34 i8 made o~ a transparent polymeric mater$al ~uch ~s polyvinyl acetate, polye~hylene, polyterephthalate and the like and the ink with which the data 36 is printed is an invisible ink which b_~ -9 visible upon exposure to either ultraviolet light or light in the infrared reginn. Although the transparent label 34 can be made of a number of materials and the ink~ can be any of a number of commercially available inks, it is necessary that : : ' 2123~
the materials chosen must be compatible with one another.
By invisible ink is any ink that ie not visible to the unaided eye or one that is transparent. Reference can be had to U.S. Patent No. 5,093,147 for an ~xample of an invisible ink responsive to infra-red light.
Invisible inXs are co~mercially available fro~ a member of supplier6 ~uch as ShAnnon Luminous Materials of Santa Ana, California, American Ultraviolet c ,~ny of Murray Hills, New Jereey, American Coding and Marking Ink Co pAny of Plainfield, New Jersey and U.V.P. Ink of San Gabriel, California.
With reference to FIG 3, a device 40 is shown whereby the label 34 can be printed with the appropriate data. The device includes a sc~nner 42 that ~cans the data on the driver's license 10 that is to be used for preparing the e~coded data message 36 so that there i8 a correspon~nce between the data on the driver'~ license and the data represented by the ~ncode~ message 36. The operator number 14, the expiration date 16, the operator's name 26 and the operator'-e address or any combination thereof can be used a~
data for the encode~ message 36. In addition, the photograph 12 can be scanned using the PDF 417 Code provided by Symbol Technology Inc. Another code that can be used in scanning the photograph 12 would be code 1 as provided by Crypto Post. With such ~c~nnln~, an enroded message would be printed upon the label 34 which upon docod~n~ would reproduce the photograpb 12. Needle6g to ~ay, the message 36 need not be ~nsoded, but may simply duplicate data on the face of the document ID.
After the driver's license 10 is sc~nned, the data is sent to an A/D co..~e~er 44 to convert the received signal from analog to digital. Optionally, the data can then be r n,~essed by a data compressor 45 if the amount of data is too voluminous. Thereafter, again optionally, the dsta can then be encrypted by an eno~y~or 48, following wh~ch the data would be e~co~ed whether it is encrypted or not, by an encoder 50. After the data is enco~e~, a label printer will print the encoded message upon a transparent label 34 using ~ 5 --,: ~
2~2~4~
invisible ink. The label printer will also inclu~e structure capable of applying an adhesive to the label.
Preferably, the adhesive is applied to the 6ide of the label where the encoded message 36 h~s been printed in invi~ible ink, so that the prin~ed portion of the l~bel will not be 6ubj ected to abrasion.
In an alternative : ~o~; -r~, where the ~r~ 10 iS
formed from laminated layer6 with the la~t layer being transparent, the enco~e~ message can be printed on such layer. Preferably, this message 36 is printed on the inside surface of the laminated layer.
When a determination i6 to be made as to the authenticity of a document 10, the examiner will be provided with a device 60 such as that shown in FIG 4. The device includes a scanner 62 that is capable of emitting light either in the infra-red region or ultra violet region, depending upon the invi~ible inX that had been applied to the transparent label 34. The ~cAnn~r will be moved relative to the document to be sc~nn~ ~nd light will be reflected from the document to the scanner to create data in the form of an image. The dat~ from the sc~n~er i8 then deco~ed by deco~r 64, pacsed through decryptor 66, if the information had been cr.~ ed, and subsequently the ~?ao~e~
message will be shown on a display 68. If the data on the display corresponds to the data on the document 10, the examiner will then have proof that the holder of the document 10 is the proper party. On the other hand, if there i~ no match, then the examiner would be alerted that he may be dealing with a forged do_ e1~.
In another embodiment, the label 34 can be printed with a magnetic ink to form the message 36 rather than invisible ink and a~ p,iate equipment could be provided for reading the magnetic message.
In addition to the data on the document 10, other information can be printed on the label to provide a hidden message. For example, information can be printed relative to past traffic violations or prior unlawful activities.
~ 2~,23~S6 Clearly, one would not desire such information be printed on the face of a do~l ~nt.
Thus, what has been shown and described is a conoept whereby a do~ L -nt issued by the goveL --~ or an industrial S concern can be provided with means for authentication without interfering with the format o~ Cuch a document.
