Video Watermarking Scheme for Resisting Collusion Atack

Recent video watermarking schemes that resist collusion attack has low effect,to solve the problem,a video watermarking scheme based on video segmentation was proposed in addition to analyzing of collusion attack features.From this scheme,cumulative histo gram was used for video segmentation.Furthermore,different watermarks were embedded into different shots under the control of secret key,and in fast motion regions of the video,the blocks which had smooth change were selected as embedding areas.Experimental results show that with the proposed scheme,the watermark is robust to collusion,frame insertion,frame removal and synchronous attacks.
