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.

First claim

What is claimed is:

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 personally identifiable information that identifies the subject whose face is portrayed in the digital facial portrait;
generating a digitally watermarked digital facial portrait as a machine-readable code in which the at least one digital watermark is embedded into the digital facial portrait such that the digitally watermarked digital facial portrait is issued to a mobile computing device of the subject and when the digitally watermarked digital facial portrait is displayed on the mobile computing device of the subject, the subject presenting the digital facial portrait is identified and authenticated by having the digitally watermarked digital facial portrait scanned such that (i) the personally identifiable information is retrieved from the digitally watermarked digital facial portrait; and (ii) the displayed digital facial portrait is authenticated based on the retrieved personally identifiable information; and
suspending or revoking the digitally watermarked digital facial portrait in response to a validated request for suspension or revocation by 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.

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 personally identifiable information that identifies the subject.

3. The method of claim 2 , further comprising:
modifying the personally identifiable information to reflect information updated by the renewal request before generating the renewed digital watermarked digital facial portrait.

4. The method of claim 1 , further comprising:
receiving a request for replacing the digitally watermarked digital facial portrait with 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 personally identifiable information that identifies the subject; and
generating the replacement digitally watermarked digital facial portrait.

5. The method of claim 4 , further comprising:
modifying the personally identifiable information to reflect information updated by the replacement request before generating the replacement digitally watermarked digital facial portrait.

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

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 , wherein suspending or revoking the digital identification document further comprises:
removing the digitally watermarked digital facial portrait from the mobile computing device of the subject.

15. 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 personally identifiable information, that identifies the subject whose face is portrayed in the digital facial portrait;
generating a digitally watermarked digital facial portrait as a machine-readable code in which the at least one digital watermark is embedded into the digital facial portrait such that the digitally watermarked digital facial portrait is issued to a mobile computing device of the subject and when the digitally watermarked digital facial portrait is displayed on the mobile computing device of the subject, the subject presenting the digital facial portrait is identified and authenticated by having the digitally watermarked digital facial portrait scanned such that (i) the personally identifiable information is retrieved from the digitally watermarked digital facial portrait; and (ii) the displayed digital facial portrait is authenticated based on the retrieved personally identifiable information; and
suspending or revoking the digitally watermarked digital facial portrait in response to a validated request for suspension or revocation by 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.

16. The system of claim 15 , 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 personally identifiable information that identifies the subject.

17. The system of claim 16 , wherein the operations further comprise:
modifying the personally identifiable information to reflect information updated by the renewal request before generating the renewed digitally watermarked digital facial portrait.

18. The system of claim 15 , wherein the operations further comprise:
receiving a request for replacing the digitally watermarked digital facial portrait with an updated digital 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 personally identifiable information that identifies the subject; and
generating the replacement digitally watermarked digital facial portrait.

19. The system of claim 18 , wherein the operations further comprise:
modifying the personally identifiable information to reflect information updated by the replacement request before issuing the replacement digitally watermarked
