We propose the effective video watermarking algorithm to protect the copyright. We use the visible binary image as the watermark. Our watermarking procedure is based on the three-dimensional discrete wavelet transform (3D DWT) and the spread spectrum sequence. We pre-process two watermark images using the mixing and the pseudorandom permutation. After dividing a video sequence into video shots, we perform the 3D DWT. And then, the watermark is embedded into the 3D DWT coefficients considering the robustness and the invisibility. At this time, we use two spread spectrum sequences define as the temporal user key. Experimental results show that the watermarked frames are indistinguishable from the original frames subjectively and the proposed video watermarking algorithm is robust enough against attacks of the low pass filtering, the frame dropping, and the MPEG coding.
