Abstract :
In the last few years, live pay-TV system via Internet has come to be established with the development of broadband network. To develop such a system, a mechanism for content protection is required. In this paper, a new architecture integrating fingerprint with cryptosystem is proposed to protect contents from unauthorized access and illegal redistribution. We describe a scheme integrating anti-collusion code and home page public-key cryptosystem. The proposed scheme is shown feasible and realistic for implementing with respect to computation/communication cost.
