Abstract

Disclosed are methods, systems and articles of manufacture for creating and authenticating self-verifying articles. Self-verifying articles include, for example, commercial instruments (i.e., notes, drafts, checks, bearer paper, etc.), transaction cards (i.e., ATM cards, calling cards, credit cards, etc.), personal identification documents (i.e., driver'"'"'s licenses, passports, personal identification papers, etc.) and labels affixed to package surfaces for identification of the package owner or sender, which, for example, may be used for verifying imported goods by customs agents. Self-verifying article creation includes receiving recipient-specific data, encoding a first selected subset of the recipient-specific data and fixing the encoded subset along with other human-recognizable data on a surface of an article. Self-verifying article authentication includes scanning a surface to locate an encoded first data set, decoding the first data set and comparing the decoded first data set with a control data set, which may also be fixed upon the surface, to determine the authenticity of the received self-verifying article.

Claims

1. A self-verifying article comprising:

a surface;

a first data set fixed upon said surface; and

a second data set fixed upon said surface, said second data set being all encoded copy of at least a portion of said first data set and being configured as an optically readable code forming at least one matrix array having a perimeter and alternating black and white symbols alone said perimeter.

2. The self-verifying article as set forth in claim 1 wherein said second data set comprises biometric data.

3. The self-verifying article as set forth in claim 1 wherein portions of said first and second data sets comprise biometric data.

5. The self-verifying article as set forth in claim 1 further comprising:

a third data set fixed upon said article, said third data set comprising textual data.

6. The self-verifying article as set forth in claim 5 further comprising:

a fourth data set fixed upon said article, said fourth data set is an encoded copy of at least a portion of said third data set.

7. The self-verifying article as set forth in claim 6 wherein said second and fourth encoded data sets are combined together forming one machine-readable data set.

8. The self-verifying article as set forth in claim 1 wherein said second data set is fixed upon said article and is undetectable to the human-eye.

9. The self-verifying article as set forth in claim 1 wherein said article is a commercial instrument and said second data set includes an endorsement of the drawer/maker/owner of said commercial instrument.

10. The self-verifying article as set forth in claim 1 wherein said article is a transaction card.

11. The self-verifying article as set forth in claim 1 wherein the article further comprises a first outer surface and a second outer surface wherein the second data set is formed as an array of voids between the outer surfaces of said article.

4. A self-verifying article comprising:

a surface,

a first data set fixed upon said surface; and

a second data set fixed upon said surface, said second data set being an encoded copy of at least a portion of said first data set,

wherein said second data set comprises biometric data and is configured as an optically readable code forming two matrix arrays.

12. A recipient-specific identification article comprising:

a surface; and

a machine-readable data set fixed upon said surface, said machine-readable data set including encoded biometric data configured as an optically readable code forming at least one matrix.

13. The recipient-specific identification article as set forth in claim 12 wherein said fixed machine-readable data set is not detectable by an unaided human-eye.

14. The recipient-specific identification article as set forth in claim 12 wherein said article is a transaction card.

15. The recipient-specific identification article as set forth in claim 12 wherein said article is a commercial instrument.

16. The recipient-specific identification article as set forth in claim 12 further comprising a textual data set fixed upon said surface, wherein said machine-readable data set includes an encoded subset of said textual data set.

17. The recipient-specific identification article as set forth in claim 16 wherein said machine-readable data set is configured as an optically readable binary code forming two matrices.

18. The recipient-specific identification article as set forth in claim 17 wherein said encoded biometric data and said encoded subset of textual data are combined to form a single data set.

19. The recipient-specific identification article as set forth in claim 18 wherein said encoded biometric data and said encoded subset of textual data are concatenated together to form said single data set.

20. The recipient-specific identification article as set forth in claim 18 wherein said encoded biometric data and said encoded subset of textual data are interleaved to form said single data set.

21. A self-verifying article comprising:

a surface;

first and second data sets;

third and fourth data sets fixed upon said surface, said third data set being an encoded copy of at least a portion of said first data set and said fourth data set being an encoded copy of at least a portion of said second data set,

wherein said third and fourth encoded data sets are concatenated, forming one machine-readable data set which is encoded as at least two matrix arrays fixed to said surface.

22. The self-verifying article of claim 21 wherein said first data set comprises biometric data and said second data set comprises textual data.

23. A self-verifying article comprising:

a surface;

first and second data sets;

third and fourth data sets fixed upon said surface, said third data set being an encoded copy of at least a portion of said first data set and said fourth data set being an encoded copy of at least a portion of said second data set,

wherein said third and fourth encoded data sets are interleaved forming one machine-readable data set which is encoded as at least two matrix arrays fixed to said surface.

24. The self-verifying article of claim 23 wherein said first data set comprises biometric data and said second data set comprises textual data.

25. The self-verifying article of claim 23 wherein each of said matrix arrays comprises a checksum for verifying data integrity of each of said matrix arrays independently.

26. The self-verifying article of claim 23 wherein each of said matrix arrays comprises a checksum for verifying data integrity of each of said matrix arrays collectively.
