The Research of Digital Copyright Protecting Mechanisms Base on Mobile Agent and Digital Watermark

Digital copyright protection is a big concern under the circumstances of Network in the world. The conventional method of copyright protection is to search information of digital works with search engine, and download them to a server where all digital works would be authenticated. A new Copyright Protecting System base on the mechanisms of digital watermark and mobile agent is proposed. The mobile agents which have evolvement ability can migrate in the Internet like spider from one node to another, and authenticate the digital watermark in digital works directly in the remote mainframe. If there are pirating problems, the results of the authentication will be sent back to the server. Therefore the conventional disadvantage of server load overweight is solved, and the copyright protecting efficiency is greatly improved. Furthermore, a communication framework of digital watermark detection agent based on KQML, XML and SOAP is also proposed to realize the mutual operation between isomerous programs and platforms.
