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.

Abstract: A web site copyright registration system and method is accomplished via a computer system that examines a web site or other work and produces completed copyright registration forms and associated materials (e.g., a copy of the web site and additional copies of selected individual web site components) to register the web site and selected individual web site components for copyright protection. The computer system, via software, receives copyright information related to the web site from a user and examines the web site to identify individual web site components contained within the web site and to ascertain component information related to each identified web site component. The user is queried by the computer system for each identified web site component to select web site components for inclusion in the web site registration. Further, the user may select identified web site components for individual copyright protection.
