In this paper,a spatial-temporal watermarking algorithm is proposed based on the spatial(2D_DCT) in frame and temporal DWT between frames.In the process of watermark embedding,DWT,which is used to extend color watermark image to an image twins,embed the watermarking information into the static and the dynamic components of the host video sequence [0].In addition,the watermark image is encrypted base on chaos theory.The experimental results demonstrate the effectiveness and robustness of the proposed algorithm.
