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.
