Abstract:

A new protocol to protect the intellectual property of digital multimedia using digital watermark was proposed. The proposition brings forward the protocols for copyright registering, watermarking embedding, watermarking detecting and dispute resolutions. The copyright owner could register his copyright information to a DRPC (digital copyright protection center), and DRPC will then decide to embed the watermark information into the media or not. Meanwhile the owner could also detect his watermark information in the watermarked media at any time. When the copyright is infracted, DRPC will be able to give an authoritative proof of the copyright for the owner in time. Analysis shows that the protocol is very secure and effective.

Key words: copyright protection, digital watermarking, watermarking protocol
