Patent Images
1. Apparatus which authenticates a digital representation of an object from which an analog form may be made, the apparatus comprising:
- an authenticator which uses first information in a first portion of the digital representation to produce first authentication information, the first information also being obtainable from a third portion of the analog form that is made from the first portion; and
an incorporator which incorporates the first authentication information in a second portion of the digital representation, the authentication information also being obtainable from a fourth portion of the analog form that is made from the second portion.

11. Apparatus for determining authenticity of a digital representation of an object, the digital representation including embedded first authentication information and the apparatus comprising:
-
a storage system in which stored second authentication information is associated with stored reference codes; and
a processor which receives the digital representation and a reference code associated therewith, the processor including an authentication information reader and the processor employing the reference code to retrieve the second authentication information associated therewith from the storage system, employing the authentication information reader to read the embedded first authentication information, and employing the read first authentication information and the second authentication information to determine authenticity of the digital representation. - View Dependent Claims (12, 13)

14. Apparatus for checking the authenticity of an analog form, the analog form including embedded first authentication information and the apparatus comprising:
-
an analog form converter that receives the analog form and makes a digital representation of at least the first authentication information; and
a communications system, the analog form converter employing the communications system to send the digital representation and a reference code to a verification system that employs the reference code and the first authentication information to determine whether the analog form is authentic and to receive a notification whether the analog form is authentic from the verification system. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of determining authenticity of a digital representation of an object, the digital representation including embedded first authentication information and the method including the steps performed in a data processing system of:
-
receiving the digital representation and a reference code associated therewith in the system;
using the reference code to retrieve second authentication information associated with the reference code;
reading the embedded first authentication information; and
employing the read first authentication information and the second authentication information to determine authenticity of the digital representation.
