Digital authentication with digital and analog documents
First Claim
1. 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.

Abstract
Techniques for incorporating authentication information into digital representations of objects and using the authentication information to authenticate the objects. The authentication information may be made from information in one portion of the digital representation and incorporated into another portion of the digital representation that does not overlap the first portion. Where the digital representation is made into an analog form and that in turn is made into a digital representation and the second digital representation is verified, the two portions must further be non-overlapping in the analog form. The information from which the authentication information is made may exist at many levels: representations of physical effects produced by the object, representations of features of the object, codes that represent the object'"'"'s contents, and representations of descriptions of the object. Also disclosed are a verification server and techniques for reducing errors by an OCR. The verification server verifies authenticated documents. When a document is verified, an identifier is associated with the document and the identifier is used to locate a key for the authentication information and in some cases a second copy of the authentication information. The verification process may also involve security patterns that are a physical part of the analog form. The error reduction techniques include an error code specifying characters in the object that are confusing to OCR devices, and the error code is used to correct the results of an OCR reading of an analog form.

12. 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.

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.
