Abstract:
We propose a new method of illegal copy protection, which is adapted to digital contents delivery service, allows for legitimate users to make private copies on arbitrary terminals within the limited times, and requires no secure hardware. Using the method, we can realize two types of services; one is a client-server model over peer-to-peer network, and the other is a broadcast model over multicast network which is similar to existing broadcast. In this paper, we implement the proposed method and evaluate whether our method is feasible from the viewpoint of security and performance.
