Abstract
An electronic system where messages include information carried by digital watermarks. The digital watermarks are used to control the transmission and/or receipt of messages including images or audio transmitted over the system. The system prevents the accidental dissemination of information to unauthorized receivers. Furthermore, while no security system is fool-proof, the system helps guards against the intentional, but unauthorized, dissemination of information to unauthorized receivers.
