Digital authentication with analog documents
First Claim
1. An apparatus to determine authenticity of an analog form, the analog form including first authentication information that is provided on the analog form so that its presence is not readily apparent to a human observer of the analog form, and wherein the first authentication information is provided through alterations to data representing imagery or graphics on the analog form, and wherein the first authentication information corresponds to or is redundant with at least some human readable information present in the analog form and that is incorporated into the analog form, the apparatus comprising:
- a human readable information reader that reads the human readable information in the analog form;
an authentication information reader that reads the first authentication information from the analog form, wherein the authentication information reader utilizes optical scan data; and
an authenticator that determines whether the analog form is authentic by reference to at least the i) first authentication information, and ii) the human readable information or information corresponding to or redundant with the human readable information.

Abstract
Security of photographic identification documents is enhanced by embedding within the photographic image encoded information that may be correlated to other information pertaining to the individual represented by the image, such other information being, for example, printed on the document adjacent to the photograph.

4. A method of providing an analog form, the method comprising:
-
producing first authentication information that corresponds to or is redundant with at least some semantic information that will be present in the analog form; and steganographically incorporating the first authentication information into the analog form, wherein the semantic information remains useful in the analog form, and wherein the first authentication information provided through alterations to data representing imagery or graphics on the analog form so that the presence of the first authentication information is not readily apparent to human observers of the analog form, whereby the first authentication information may be retrieved from the analog form and compared with the semantic information in the analog form or information corresponding to or redundant with the at least some of the semantic information to determine authenticity of the analog form. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. A method to provide a physical article including semantic information, said method comprising:
-
providing plural-bit information, wherein the plural-bit information corresponds to or is redundant with at least a portion of the semantic information; and steganographically providing the plural-bit information on the physical article, wherein the information is provided through alterations to data representing imagery or graphics on the physical article so that the presence of the information is not readily apparent to human observers of the physical article, wherein the plural-bit information is provided so as to be machine-readable from optical scan data of at least a portion of the physical article. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method to provide a physical article including semantic information, said method comprising:
-
providing plural-bit information, wherein the plural-bit information corresponds to or is redundant with the semantic information; and providing the plural-bit information on the physical article, wherein the plural-bit information is provided so that its presence is not readily apparent to human observers of the physical article, yet can be detected from visible light scan data generated by visible light scanning of the physical article. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method to provide a physical article including semantic information, said method comprising:
-
providing plural-bit information, wherein the plural-bit information corresponds to or is redundant with at least a portion of the semantic information; and steganographically providing the plural-bit information on the physical article, wherein the machine-readable code is provided on the article so that its presence is not readily apparent to human observers of the article, yet can be detected from scan data generated by visible light scanning of the article, wherein the plural-bit information is provided so as to be machine-readable from optical scan data of at least a portion of the physical article.

36. A method of providing an analog form, the method comprising:
-
producing first authentication information that corresponds to or is redundant with at least same semantic information that will be present in the analog form; and steganographically incorporating the first authentication information into the analog form, wherein the semantic information remains useful in the analog form, and wherein the first authentication information is provided on the analog form so that its presence is not readily apparent to human observers of the analog form, yet can be detected from scan data generated by visible light scanning of the analog form, whereby the first authentication information may be retrieved from the analog form and compared with the semantic information in the analog form or information corresponding to or redundant with the at least some of the semantic information to determine authenticity of the analog form.
