ABSTRACT:
A method of data hiding includes providing a message (68), providing an encrypting sequence (86), and generating an encrypted message (72) based on the message and the encrypting sequence. A carrier signal (66) that conveys information unrelated to the encrypted message is provided, and the encrypted message is embedded (78) into the carrier signal by performing an exclusive-OR of the encrypted message with a first portion of the carrier signal.
