Abstract—Resisting collusion attack is one of important performances of video watermark algorithm. This paper presents a novel video watermark algorithm based on the visual features of the host video. The proposed algorithm embeds watermark on the DWT coefficients of sub-regions. The mechanism of JND (just-noticeable distortion) is used to attenuate the embedding strength in the sub-region. Experimental results show the proposed scheme can effectively resist two types of linear collusion attacks while still being robust, stable and imperceptible.

Index Terms—Video watermark, collusion attack, content, sub-region.
