There is great potential for increasing a user's productivity and comfort level by creating a more personalized computing experience. Currently, most users change few or none of the default operating system settings. Users stick with the default settings each time a new system is used because of the inconvenience of configuring a computing environment. A physical disability preventing a user from changing the settings or a lack of knowledge on how to do this are among the other reasons why a user may remain with the default settings.
The current computer desktop environment stores one profile of settings for each account on the system. If a user of one computer wants his or her custom settings on another computer, there are currently two options. The user can create an account on the other computer and then customize the settings of the new account or the user can use an existing account on the other computer and manually change the settings as desired. The first option requires a user with the proper access to create an account. The user must then customize the environment. If this computer is located in a public setting, it may not be practical to create an account for so many one-time users. The problem with the second option is that once the settings are changed, each subsequent user is forced to conform to these settings or change them again. Either scenario discourages users from customizing their computing environment.
An object of this invention is to allow a user to temporarily change settings, which have no impact on system security, to the custom settings that a user desires. The custom settings allow for instant familiarity, thereby resulting in increased productivity and less extraneous accounts. Unlike the current computing environment, a user does do not need to have a profile or an account on the computer, and can automatically and transparently use the desired settings.
Another object of this invention is to allow for the personalization of an Internet environment. Many websites require a logon and password for access. If a user has logged on from the same computer before, it is possible that this information is stored on the hard drive as a cookie allowing the user to bypass the logon process. If the user were to go to another computer, it would be necessary for the user to logon to verify the user's identity. This invention allows the logon information to be stored on the card and used on any computer. The viewed website will signal the web browser to execute a program that will determine if any cards are in a predetermined range. Upon detection of a card within the predetermined range, and if a card is in range and contains an account for that website, the user can transparently be logged on. Otherwise, the normal prompt for a user name and password appears.
The ability to transparently import the information stored on the card into the current computing environment creates the impression to the user that they have an account on the computer. Every computer that the user accesses will have the same look and feel that they are accustomed to. The ability to store email address and Internet favorites in addition to other data on the card allows users to have their personal list of email addresses at their fingertips regardless of which computer they are using.
In one embodiment of the invention, a contact smart is card is employed. The contact smart card only requires users to insert their card into the reader when they arrive and remove it when they depart. A contactless smart card permits users to keep the card in their wallet or in close proximity to the reader. When the user is within the predetermined range of the reader, the settings will automatically be established on the corresponding computer, and when the user leaves the range, the settings will automatically revert back to predetermined settings.
An advantage to this invention is that it assists disabled individuals with their computing experience. There are many people who have trouble using a computer due to disabilities such as colorblindness, bad vision and poor dexterity. Some operating systems do provide mechanisms to assist these users; however, accessibility software requires the user to reconfigure such personalized settings each time a new computer is used. For example, the Microsoft Windows operating system comes with accessibility software, but a user dependent on this software can use only a PC on which those settings are currently active. If a user has poor vision or color blindness he or she can use the accessibility software to make the colors on the screen appear in high contrast mode. This setting now allows the user to be productive on a computer despite his or her disability. The problem with this setup is that the disabled user cannot use any computer, they either need to struggle with the computer to set the desired accessibility settings, or obtain assistance from others to properly configure the computer.
Another problem is that a user is unable to then port his or her desired settings from PC to PC. If a disabled user were to use a public computer at a library he or she would have to go through the process of setting up the accessibility features every time the computer was used. This would be a great burden on the user and on the people who may be required to repeatedly assist in this process This invention would allow disabled individuals to configure their smart card settings only once, or buy a preconfigured smart card, and then have all computers automatically switch to a mode where they are able to use the computer with no assistance from others. A user with poor dexterity can now setup the mouse and keyboard settings only once on their smart card and have every computer they use after that change to the desired settings with no further interaction by the user. Not only would this make life easier for individuals with disabilities, it would also increase their interaction with computers because they will no longer require assistance to operate a computer.
This invention also has the advantage of assisting individuals with making their computing experience more comfortable and intuitive. For example, most computers by default are setup to work with a right-handed mouse. Left-handed individuals are forced to conform to the mouse button setup for right-handed person or reconfigure the computer to operate with left-handed mouse buttons. This invention will now allow left-handed people to sit down at any computer and have the mouse buttons transparently switch. This increased comfort level for users can also be realized in a multicultural computing environment. Personal settings can be used to specify the language that a user wishes to be displayed on the computer. This would be of aid to travelers at airports and other locations with people of varying languages. A user at an airport computer who is purchasing tickets can have the ticket information and prices automatically displayed in the language specified on their smart card.
In a preferred embodiment of the present invention, personalized preference settings are stored on a smart card or other data carrier. Preferably, the smart card will have a similar look and feel to that of a credit card. The card format allows users to save their settings to a card for facile transportation and concealment.
In one embodiment, the smart card is contactless, meaning that it is not required to insert or physically couple with a receiver. In such an embodiment, the smart card can be left in a wallet the card and will not require removal for a receiver to detect and access. Current contactless cards communicate with the receiver through radio frequency but another wireless method may be used to transfer the data from the smart card to the receiver. The combination of the card format and wireless communication enables the card to easily travel with and be used without any intervention by the user. The card can also have contacts, which would require a user to insert the card into the reader.
In another embodiment, the card can be a combination of a contact and contactless card allowing for operation with both types of readers. The cards can also come in the formats of read-only and read-write, and can vary in their storage capabilities. As smart card technology advances, card memory capacity will grow allowing users to store even more information.
The data stored on the smart card may also be compressed to allow for greater storage.
There are a numerous settings that this invention can store on a smart card for automatic retrieval and configuration on another computer.

The reader 314 should be placed within close proximity to the computer 310, 312 to allow it to detect when a user intends to use the computer 310, 312. As illustrated in
If two contactless cards come in the range of the receiver 616 at the same time while another smart card is not currently in use, anti-collision handling software would determine which card is selected. Users also have the option to turn the receiver 616 off or, if more than one card is within range of the receiver 616, manually switch the card being read. Once smart cards settings are loaded, those settings remain the dominant settings until that card leaves the range of the reader, the user chooses to switch manually to another smart card, or the user decides to manually revert to the original system settings and not use smart card settings.
The software system is composed of four components. The first component consists of the interface between the card and the computer. The interface is designed to be compatible with the Personal Computer/Smart Card (PC/SC) standard or any other industry standard that may replace it in the future. The use of the PC/SC standard enables the software to be interoperable with any card/receiver combination that conforms to the standard. The second component reads the settings from the card and modifies the computer environment to reflect these new settings. This component runs in the background on the computer. It would run as a service on the Microsoft Windows Operating System environment. Running this component as a service allows the software to be active across multiple accounts while providing it the proper access privileges to change the desired settings. The third component is an easy to use graphical interface that allows a user to easily customize settings and save those settings to the device for later use. This component would also allow users to modify and view which settings are currently contained on a smart card. The fourth software component handles the protocol used to allow the card to interact with the Internet. More specifically, it allows users to transparently logon to Internet sites using information stored on the smart card in conjunction with software integrated into a web browser and website.
As demonstrated in the flow chart of
The predetermined range in which the reader scans will come with a default setting that is applicable to most environments, but users will be able to adjust this setting if desired. Once a smart card is detected 14 by the reader, the software attempts to retrieve 22 the unique ID and checksum of the data contained on the card. If the owner of the smart card decided to encrypt the data contained on the card, he or she would be prompted 18 and required to enter the proper personal identification number (PIN) to proceed with the transfer of information from the card. It is envisioned that most users will have no desire to protect their personal settings, so in the majority of cases no user interaction would be required to transfer the settings from the card to the computer. The reason why most users would most likely choose not to protect the settings with a PIN is because the settings data being transferred would not be sensitive information. Not many people will be concerned with protecting their preferred mouse speed or font style.
The system is also capable of transferring the settings on the card to the computer with no PIN while having other information on the card, which is not automatically transferred, protected by a PIN. This allows the user to enjoy the ease of automatically switching settings, while still allowing for other information to be password protected and only transferred upon request by the user at which time they will be required to enter a PIN.
Once the software receives 22 the unique ID and data checksum from the smart card, it inspects 24 the settings cache on the computer to see if this user has previously altered the settings. Each card contains a globally unique identifier (GUID) 412 that uniquely identifies the card.
A GUID is an alphanumeric identifier that is unique across time and space. The card also contains a current checksum 414 of the all data contained on it. The GUID 412 and checksum 414 are used to implement a local caching system to allow for a faster transfer and configuration of the settings. When the receiver detects 14 a card, it obtains the GUID on the device along with the checksum and compares the two pieces of data to the entries in the smart card cache on the computer. If the GUID of the device does not exist in the cache, or the GUID exists but the checksum differs, then the entire collection of settings must be transferred 26 from the device to the computer. If the GUID exists in the cache and if the checksum on the card matches the checksum of the settings stored in the cache, then the computer already has a current copy of the data and that data can be used instead of transferring it from the card.
If the data from the smart card is encrypted 30, then the PIN entered by the user is used to decrypt this data. Likewise, if the data from the smart card has been compressed 28, it is decompressed at this point. The compression of the settings allows for more information to be stored on the smart card and for faster transfer of information from the smart card to the computer. The use of compression provides a great advantage since smart card memory and settings transfer speed are vital to this invention.
The software then saves 32 all of the settings currently in use by the computer so that the system can revert back to these settings after the smart card user leaves the radius of the reader. The process of saving the current settings involves packaging the information into a file and writing it to the hard disk. The current settings are persisted to the disk to allow the restoration of the appropriate settings if the computer is not properly shutdown while smart card settings are active. After a user's current settings have been saved 32, the software reads the settings file retrieved from the smart card or from the settings cache and then activates the settings 34 on the current system. At this point users can see the settings changing, such as the wallpaper, window title bars and other settings that affect the visual interface. When all of the settings have been changed, users will be notified by the icon in the system tray. These new settings remain active until the smart card reader detects that the smart card is no longer present 50. The smart card is considered no longer present when the reader does not detect a smart card containing the GUID currently in use for a specified amount of time. This specified amount of time could be changed by the system administrator.
If users change the system settings while the smart card settings are active 36 they have the option to save these changes to the card 38, resulting in an updated preference set. Depending on a user's settings, these updated settings can be automatically transferred to the card or the user can be prompted whether to save the new settings or not. By default, any settings changes made when the smart card is active will automatically be saved to the card. This gives users the transparent non-interactive interface that this invention embodies. If there are new settings to be transferred to the card, the software collects these new settings 40 and prepares them for transfer to the card.
The first step in preparing the new data to be transferred to the card requires the computation of a new checksum value for the data to be written to the card. This checksum computation 40 can be performed using the well-known MD5 hash algorithm, or any other established hash algorithm. If a user has specified encryption for the data, the settings file is then encrypted 42. Likewise, if a user has specified compression, the data is then compressed 44. After these steps have been completed, the settings and checksum value are then transferred 46 to the smart card. These new settings and the checksum value are also transferred to the computer's settings cache 48 where they replace the previous information for this user.
After the reader determines that a smart card is no longer present 50, the system checks for the existence of original settings 52. If these settings are found, the software changes the system back to these original settings 54. At this point, if anyone is watching the computer, they will see the user interface elements affected by the smart card settings revert back to their original state. The icon in the system tray will notify the user that this transformation is taking place. When the transformation to the original settings is complete, the system tray icon will appear in the polling state 12, indicating that the system is again ready to accept smart card settings.
In addition to settings, the user is also given the capability to add to the list of items stored on the card. As shown in
The security cautious user is given several options to provide different levels of protection for the information stored on the card. According to personal preferences the user has the option of requiring the entry of a PIN 18 prior to the transfer of information from the card to the computer. With this option enabled the information stored on the card is encrypted and can only be decrypted though the PIN. The user can either require a PIN for all data on the card or for only a subset of the data. For example, the user may allow the personalized settings to be automatically accessed but require a PIN to access a data file that has been stored in user defined storage area. The user is also given the option to set an expiration date 416 for the card. This allows the card to be used without entry of the PIN for specified amount of time. In order to use the card after this time has passed, the user must enter a PIN.
As shown in
After the installation of the smart card settings software, a graphical program can be run, enabling users to easily personalize their settings and then save those settings to a smart card. The software lets the user browse different categories of settings initialized to the values of the current computer system. A user is free to modify any of the values to obtain the desired environment. A user is free to either personalize all of the possible settings presented by the software or to only select a subset of these settings to travel with the smart card to other computers. The personalization software suspends the computer's ability to switch to smart card settings while it is running. This allows a users smart card to enter the range of the reader and have the current computer settings written to the card without the computer switching to the settings currently contained on the card.
Once the settings are modified as desired a user can press a button on the software interface that saves these settings to a smart card. A new GUID is generated and written to the card along with the settings information. After the settings have been saved, the personalization program can be exited and the card is now ready to be used on any computer running the smart card settings software. The personalization program can be repeated as many times as necessary on each card. The personalization program also allows the user to configure the smart card for logon to websites that support smart card logon.
Turning to the diagram in
The card expiration info 416 is used to determine when the card can no longer be freely accessed. If no date is specified then this option is not used. After the date contained in the card expiration is reached a PIN will be required for further access to the data. The card also contains two boolean flags. The settings PIN flag 418 notifies the computer if a PIN is required to access the settings on the card. The additional data PIN flag 422 notifies the computer if a PIN is required to access the additional data contained on the card. A series of website identifiers 426 and their corresponding logon information 426 are also stored on the card. This section of identifiers determines the web sites that can be transparently logged into when the computer is connected to the Internet. The additional data section 424 contains information the user has decided to store on the card. This can be any arbitrary data supplied by the user. The graphical settings personalization program will allow users to easily drag and drop files and other data onto an additional data section that will be written to the card. The settings information file 420 contains all of the settings that will automatically be transferred and activated when the card enters the range of a card reader.
In most cases, when a user first obtains a smart card it will not contain any settings information. The card will need to be configured to contain the users personal settings. However, it is possible to obtain preconfigured smart cards. These preconfigured cards can contain certain desktop themes or they can be preconfigured to aid people with certain disabilities so that no setup is required. For example, a user with colorblindness can buy a card that by default changes the computer to high contrast mode. Desktop theme cards would have a set of preferences stored on the card to give the computer a particular look and feel.
A user may have several different cards each configured for a different use. If a user frequently uses a computer for different tasks it may be beneficial to have different environments setup that best suit the current task. A user can populate the current environment with relevant email addresses and websites for a work environment on one card, and then have another card to populate the environment for recreational use. Business may also choose to give out preconfigured cards as a means of advertisement. The card can contain the company's website, email addresses, and other relevant information. For example, a restaurant can place their menu and address information on the card. When the customer wants more information than is printed on the card it can be brought into the range of the reader and the relevant information will become visible on the computer screen.
The present invention is not limited to use on a computer terminal, but can be used on any application device in which a smart card reader is equipped. Such application devices include Internet kiosks, telephones, televisions or any other device wherein personal preference settings are used.
