A novel alogrithm is proposed about video watermark. FCM alogrithm is utilized to select adaptive proposal direction to motion vector by the direction clustering character of motion vector. The watermark is embeded that motion vectcor selected. The proposed algorithm is simple and efficient. Moreover, watermark can be extracted blindly without original images. The result of experiment indicate, the watermark embeded by this alogrithm can resist various attack such as frame deleted, frame inserted. The watermark is extreme robust.
