Collusion-resistant blind video watermarking based on H264

In this paper, a video watermarking scheme is proposed to make the watermarked video sequence robust against collusion attacks. Now the temporal correlation between adjacent video frames poses a severe challenges for video watermarking applications,. If the same or redundant watermarking is used for embedding in every frame of video, the watermarking can be estimated and then removed by watermark estimation attack., also if uncorrelated watermarks are used for every frame, these watermarks can be washed out with frame temporal filtering. The algorithm uses a method of high-precision motion compensation which presented in H.264.The experiment results shows that the algorithm can resist the collusion attacks effectively.
