A Network for Copyright Management and Control of Private Information

Because of a distribution of copyrighted contents and private information on IT enable networks, copyright management and control of private information for the distribution became serious problems. In this paper, we show the relationship between rights management and the control of private information, and investigate the network that is suitable for them. We propose the method of communication between an information distributor and an agent accompanying the information over an anonymous channel. Moreover, an anonymous-routing method for locating a position of distributed data has been proposed based on traces of routing history. By applying this method to the system that treats the private information, owners of information can control the purpose of content usage and protect the integrity of information.
