Robust digital video watermarking algorithm against collusion attack
一种抵抗共谋攻击的数字视频水印算法

To improve the collusion attack of the video watermark, video content features were studied in domain of diacrete cosine transform, the algorithm in which both watermark information and its position information depend on content of embedded point was presented. Finally, experiment was performed to detect robustness of the algorithm. The result demonstrats that the algorithm is robust to collusion attack.
