摘要
In this paper, a secure multimedia distribution scheme resistant to collusion attacks is proposed. In this scheme, the multimedia content is modulated by n pseudorandom sequences at the server side, which generates the unintelligible multimedia content, and then demodulated under the control of the fingerprint code at the customer side, which produces the multimedia content contains a unique code. The demodulation process adopts collusion-resistant fingerprint codes to determine which sequences will be removed from the received multimedia content. Since the collusion-resistant fingerprint code is used, the colluders who combine different copies together can be detected. Compared with existing schemes, the collusion-resistant code is used in the proposed scheme, which, confirms the robustness against collusion attacks. This scheme provides a good choice for secure multimedia content distribution.
