Video watermarking scheme for resistance to linear collusion based on diversity technique
基于分集技术的抗线性共谋攻击的视频水印方案

This paper gave the mathematical model of linear collusion attack. And according to the model, put forward the design framework of video watermarking for resistance to linear collusion based on the communication diversity technique. Moreover, it proposed an adaptive video watermarking scheme, which was in spatial domain, for effective resistance to linear collusion attack according to the proposed framework. Theory analysis and experiment show that watermark can not only be robust enough to cropping, frame removal, frame insertion, frame reorganization, imperceptible geometrical distortion and linear collusion, but also reduce the impact of H.264 compression under some conditions.
