Robust digital video watermarking algorithm against collusion attack
Xiaochuan Wu · Journal of Computer Applications · 2006
To improve the collusion attack of the video watermark, video content features were studied in domain of discrete 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.
