摘要
Digital or analog objects are steganographically encoded with plural bit digital data. The encoding may proceed with reference to biometric data, such as fingerprint or retinal scan data. One application of such technology is to encode identification documents, such as a drivers' licenses. The encoded data can later be decoded and used, e.g., for authentication purposes.
