Abstract

The present invention relates to a highly secure personal identification related document. In one implementation, the highly secure personal identification related document is achieved by having an area which contains machine readable information and also having a printed region having embedded data in the image printed thereon.

Claims

1. A personal identification related document reader system comprising:

means for reading a machine readable area of a personal identification related document;

an optical scanner for scanning a printed image area of the personal identification related document;

means for extracting data embedded with an image in the printed image area;

a hash algorithm for deriving information from the machine readable area;

means for comparing the information derived from the machine readable area to the extracted data embedded within the printed image area; and

an indicator device which informs a user if the information derived from the machine readable area and the extracted data embedded within the printed image area are within a predetermined level of agreement, the predetermined level of agreement being less than 100 percent.

2. A personal identification related document reader system as recited in claim 1 wherein:

the machine readable information is in a magnetic strip.

3. A personal identification related document reader system as recited in claim 1 wherein:

the machine readable information is in a two-dimensional bar code.

4. A personal identification related document reader system as recited in claim 1 wherein:

the machine readable information is in an integrated circuit.

5. A personal identification related document reader system as recited in claim 1 wherein:

the machine readable information is in a data structure.

6. A personal identification related document as recited in claim 1 wherein:

the printed image information in the printed region is an image of the holder the personal identification related document.

7. A personal identification related document reader system as recited in claim 1 further comprising:

a personal identification related document transport system.

8. A personal identification related document reader system as recited in claim 7 wherein:

said personal identification related document is a transaction card.

9. A method for verifying authenticity of a personal identification related document having a hash algorithm encoded first data set recorded on a machine readable area and a second data set derived from the first data set embedded in an image printed on a printed region, the method comprising the steps of:

scanning the image in the printed region;

extracting the second data set from the image in the printed region;

reading the encoded first data set;

decoding the hash algorithm encoded first data set;

deriving the second data set from the first data set of said decoding step;

comparing the second data set from said deriving step with the second data set from said extracting step; and

determining whether the second data set from said deriving step and the first data set from said extracting step are within a predetermined level of agreement, the predetermined level of agreement being less than 100 percent.

10. A method as recited in claim 9 wherein:

the image to be printed onto the printed region is an image of the holder the personal identification related document.

11. A personal identification related document reader system comprising:

means for reading a machine readable area of a personal identification related document;

an optical scanner for scanning a printed image area of the personal identification related document;

means for extracting data embedded with an image in the printed image area;

an algorithm for obtaining information from the machine readable area;

means for comparing the information obtained from the machine readable area to the extracted data embedded within the printed image area; and

an indicator device which informs a user if the information obtained from the machine readable area and the extracted data embedded within the printed image area are within a predetermined level of agreement, the predetermined level of agreement being less than 100 percent.

12. A personal identification related document reader system comprising:

means for reading a machine readable area of a personal identification related document;

an optical scanner for scanning a printed image area of the personal identification related document;

means for extracting data embedded with an image in the printed image area;

an algorithm for deriving information from the machine readable area;

means for comparing the information derived from the machine readable area to the extracted data embedded within the printed image area; and

an indicator device which informs a user if the information derived from the machine readable area and the extracted data embedded within the printed image area are within a predetermined level of agreement.

13. A personal identification related document reader system comprising:

means for reading a machine readable area of a personal identification related document;

an optical scanner for scanning a printed image area of the personal identification related document;

means for extracting data embedded with an image in the printed image area;

an algorithm for deriving information from the machine readable area;

means for comparing the information derived from the machine readable area to the extracted data embedded within the printed image area; and

an indicator device which informs a user if the information derived from the machine readable area and the extracted data embedded within the printed image area are within a predetermined level of agreement, wherein the predetermined level of agreement comprises zero percent.

14. A method for verifying authenticity of a personal identification related document having an algorithm encoded first data set recorded on a machine readable area and a second data set derived from the first data set embedded in an image printed on a printed region, the method comprising the steps of:

scanning the image in the printed region;

extracting the second data set from the image in the printed region;

reading the encoded first data set;

decoding the algorithm encoded first data set;

deriving the second data set from the first data set of said decoding step;

comparing the second data set from said deriving step with the second data set from said extracting step; and

determining whether the second data set from said deriving step and the first data set from said extracting step are within a predetermined level of agreement.

15. The method of claim 14 wherein the predetermined level of agreement comprises less than 100 percent.

16. The method of claim 14 wherein the predetermined level of agreement comprises zero percent.
