System and method for digitally watermarking digital facial portraits
First Claim

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.

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.

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; andsuspending 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations 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 the personally identifiable information is retrieved from the digitally watermarked digital facial portrait and correlated to determine that the digitally watermarked digital facial portrait being displayed is authentic; 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. - View Dependent Claims (25, 26, 27, 28)
