Abstract	The need for an electronic copyright management system (ECMS) that protects intellectual property rights (IPR) in open network environments continues to grow. Network security issues are classically handled through cryptography; however, cryptography ensures confidentiality, authenticity, and integrity only when a message is transmitted through a public channel, such as an open network. It does not protect against unauthorized copying after the message has been successfully transmitted. Digital watermarking is an effective way to protect copyright of multimedia data even after its transmission. A watermark, embedded in the data, can uniquely identify the document's owner or authorized user. The main problem with using watermark technology, for IPR protection, however, is its reversibility. Anyone who can read or detect the watermark can also remove it by inverting the watermark process. Our open network ECMS combines watermarking with cryptography to achieve reliable copyright protection while satisfying two contrasting requirements: actors in ECMS transactions must be able to verify that the watermark granting their rights is truly embedded in the multimedia document; and actors (other than the author) must not be able to remove the watermark.
