Digital watermarks have been proposed to protect legal owners from piracy--illegal copying and retransmission. However, many research problems remain open, and watermarking techniques are themselves vulnerable to piracy. This article collects fundamental watermarking concepts and offers a general watermarking framework for protecting the copyright of digital products. Registration of watermarked products is proposed for developing a trustworthy overall protection system.
