摘要

A fragile watermarking scheme suitable for the complete authentication of H.264/AVC video content is proposed in this paper. The proposed algorithm first generated authentication code according to the encoding mode of macroblock, and then embedded them into video frame by the modulation of the Motion Vector (MV). By introducing the rate distortion cost during the process of modulating, the proposed scheme achieved a better balance of rate-distortion. This authentication of video merely needs decoding modes and motion vector, which meets the requirement of the real-time processing of video. Experimental results show that it has smaller influence on the video quality and its bit rate, and can effectively carry out the certification of video frame.
