Joint Multimedia Fingerprinting and Encryption: Security Issues and Some Solutions

In this paper, a new multimedia joint fingerprinting and encryption (JFE) scheme embedded into the advanced access content system (AACS) is proposed. Like other security-related systems, there exist some security threats to the proposed framework. To cope with these difficulties, the contributions of this paper include: (i) we apply multimedia encryption at different points to resist some attacks points; and (ii) we propose rewritable fingerprint embedding (RFE) to deal with some multi-point collusion attacks. Experimental results are provided to demonstrate the proposed AACS-compatible JFE method.
