Image steganography system featuring perceptually adaptive and globally scalable signal embedding

摘要

An identification code signal is hidden in a carrier signal (such as an electronic data signal or a physical medium) in a manner that permits the identification signal later to be discerned. The carrier signal can thereby be identified, or some machine responsive action can thereby be taken. In one image steganography embodiment, the relative strength of the identification code signal is both perceptually adapted in accordance with psychovisual characteristics of the image, and globally scaled in accordance with a user-set visibility control. The technique can be applied in video imagery embodiments to control associated video equipment, e.g. to serve as a copy control signal.
