摘要

In fingerprint-based secure multimedia distribution systems, the encryption process is performed at the sender side before transmission, and the fingerprint embedding and decryption processes are performed at the receiver side simultaneously. In this paper, a low complexity joint fingerprint and decryption (JFD) scheme based on exclusive-or operations has been proposed, which can be effectively used for traitor tracing. The scheme encrypts only sub-pixels of the entire image using a tiny lookup table generated by a stream cipher. In the decryption process, some pixels can be completely recovered and the fingerprinting process depends on four different directions of sub-image blocks. The method successfully leaves the user's fingerprint during decryption and produces slightly different media copies. The experimental results show that the proposed scheme is highly effective in terms of perceptual security and fingerprinted visual quality.
