Identification Documents and Authentication of Such Documents
First Claim
1. An apparatus to authentic an identification document, the identification document comprising first machine-readable information including a first plural-bit message, and semantic information carried on or in the identification document, said apparatus comprising:
- a first reader to read the first machine-readable information to obtain the first plural-bit message;
a second reader to obtain information from the semantic information carried on or in the identification document, a decryption unit to decrypt the first plural-bit message or the information obtained from the semantic information, a decision unit to determine whether the identification document is authentic based at least in part on the first plural-bit message and the semantic information.

Abstract
The present invention relates generally to identification documents. In one implementation, a provided method includes: obtaining optical scan data associated with text characters provided on an identification document to obtain first data; using at least a portion of the first data to facilitate decryption of information—not the text characters—carried on or in the identification document. The information corresponds to the identification document or to an authorized bearer of the identification document. In another implementation, a method is providing including: obtaining optical scan data associated with an identification document to obtain first data; obtaining second data from the identification document, the second data comprising encrypted data; communicating the encrypted data and the first data to a remote device, the remote device decrypting the encrypted data with at least reference to the first data; and receiving decrypted data from the remote device. Other implementations and embodiments are provided as well.
