Abstract

Some implementations may include a method for watermarking an identification document, the method including: modulating a spatial luminance pattern associated with a first digital watermark to encode a first portion of personally identifiable information; modulating a spatial chrominance distribution associated with a second digital watermark to encode a second portion of the personally identifiable information; and applying the first digital watermark and the second digital watermark to the identification document.

Claims

1. A computer-implemented method for generating a digitally watermarked digital facial portrait, the method comprising:

receiving, at a processor, a digital facial portrait of a subject;

applying at least one digital watermark to the digital facial portrait, the at least one digital watermark encoding payload data linked to the subject; and

generating a digitally watermarked digital facial portrait as a machine-readable code for identifying the subject.

2. The method of claim 1, further comprising:

receiving a request to renew the digitally watermarked digital facial portrait; and

generating a renewed digitally watermarked digital facial portrait after verifying the renewal request, the at least one digital watermark encoding the payload data linked to the subject.

3. The method of claim 2, further comprising:

modifying the payload data to reflect information updated by the renewal request before generating the renewed digitally watermarked digital facial portrait.

4. The method of claim 1, further comprising:

receiving a request for replacing the digitally watermarked digital facial portrait and an updated digital facial portrait of the subject;

in response to determining that the request is genuine, applying the at least one digital watermark to the updated digital facial portrait to encode the payload data linked to the subject; and

generating the replacement digitally watermarked digital facial portrait.

5. The method of claim 4, further comprising:

modifying the payload data to reflect information updated by the replacement request before generating the replacement digitally watermarked digital facial portrait.

6. The method of claim 1, wherein issuing the digitally watermarked digital facial portrait comprises issuing the digitally watermarked digital facial portrait to a mobile computing device registered under the subject'"'"'s name.

7. The method of claim 1, further comprising:

securing the digitally watermarked digital facial portrait to prevent an alteration thereof.

8. The method of claim 7, wherein securing the digitally watermarked digital facial portrait comprises generating a quantitative index based on the digital facial portrait.

9. The method of claim 8, wherein generating the quantitative index comprises generating a digital certificate of at least a portion of the digital facial portrait.

10. The method of claim 8, wherein generating the quantitative index comprises generating an encryption of at least a portion of the digital facial portrait using a private key of an issuing entity.

11. The method of claim 8, wherein generating the quantitative index comprises generating a hash of at least a portion of the digitally watermarked digital facial portrait, or a digest of at least a portion of the digital facial portrait.

12. The method of claim 8, wherein generating the quantitative index comprises generating a checksum of at least a portion of digital facial portrait.

13. The method of claim 8, wherein generating the quantitative index comprises generating a version control number to indicate a current version number.

14. The method of claim 1, further comprising:

suspending or revoking the digitally watermarked digital facial portrait in response to a validated request for suspension or revocation.

15. The method of claim 14, wherein suspending or revoking the digital identification document comprises:

removing the digitally watermarked digital facial portrait from a mobile computing device of the subject.

16. The method of claim 14, wherein suspending or revoking the digital identification document comprises:

generating a suspended or revoked digitally watermarked digital facial portrait to over-write the previously generated digitally watermarked digital facial portrait on the mobile computing device of the subject.

17. A system for generating a digitally watermarked digital facial portrait, the system comprising at least one computer processor configured to perform the operations of:

receiving a digital facial portrait of a subject;

applying at least one digital watermark to the digital facial portrait, the at least one digital watermark encoding payload data linking the subject; and

generating the digitally watermarked digital facial portrait as an identification of the subject.

18. The system of claim 17, wherein the operations further comprise:

receiving a request to renew the digitally watermarked digital facial portrait; and

generating a renewed digitally watermarked digital facial portrait after verifying the renewal request, the at least one digital watermark encoding the payload data identifying the subject.

19. The system of claim 18, wherein the operations further comprise:

modifying the payload data to reflect information updated by the renewal request before generating the renewed digitally watermarked digital facial portrait.

20. The system of claim 17, wherein the operations further comprise:

receiving a request for replacing the digitally watermarked digital facial portrait and an updated digital facial portrait of the subject;

in response to determining that the request is genuine, applying the at least one digital watermark to the updated digital facial portrait to encode the payload data linked to the subject; and

generating the replacement digitally watermarked digital facial portrait.

21. The system of claim 20, wherein the operations further comprise:

modifying the payload data to reflect information updated by the replacement request before issuing the replacement digitally watermarked digital facial portrait.

22. The system of claim 17, wherein generating the digitally watermarked digital facial portrait comprises providing the digitally watermarked digital facial portrait to a mobile computing device held by the subject.

23. The system of claim 17, wherein the operations further comprise:

securing the digitally watermarked digital facial portrait to prevent an alteration thereof.

24. The system of claim 23, wherein securing the digitally watermarked digital facial portrait includes generating at least one of:

a digital certificate of at least a portion of the digitally watermarked digital facial portrait, an encryption of at least a portion of the digitally watermarked digital facial portrait using a private key of an issuing entity, a hash of at least a portion of the digitally watermarked digital facial portrait, a digest of at least a portion of the digitally watermarked digital facial portrait, or a checksum of at least a portion of the digitally watermarked digital facial portrait.

25. The system of claim 17, wherein the operations further comprise:

suspending or revoking the digitally watermarked digital facial portrait in response to a validated request for suspension or revocation.

26. The system of claim 25, wherein suspending or revoking the digital identification document comprises:

removing the digitally watermarked digital facial portrait from a mobile computing device of the subject.

27. The system of claim 26, wherein suspending or revoking the digital identification document comprises:

generating a suspended or revoked digitally watermarked digital facial portrait to over-write the previously generated digitally watermarked digital facial portrait on the mobile computing device of the subject.

28. A computer-readable medium, comprising information encoding a digitally watermarked digital facial portrait of a subject, the digitally watermarked digital facial portrait generated by:

receiving a digital facial portrait of a subject;

applying at least one digital watermark to the digital facial portrait, the at least one digital watermark identifying payload data linked the subject; and

producing the digitally watermarked digital facial portrait as a machine-readable code to identify the subject.
