Abstract

See full text

The present invention relates generally to embedding auxiliary data and data hiding. One claim recites a method including: calculating with a processor or electronic circuitry characteristics of a media signal comprising audio or video; based at least in part on calculated characteristics of the media signal, providing a map of the media signal, wherein the map identifies at least one portion of the media signal in which plural-bit data should be steganographically encoded; transforming at least some portions of the media signal into a transform domain; and steganographically encoding with a processor or electronic circuitry auxiliary data in data representing at least the one portion of the media signal in which the plural-bit data should be steganographically encoded, and wherein at least said act of transforming or said act of steganographically encoding utilizes the map of the media signal. Other claims and combinations are also provided.
