With the fast development of computer and network techniques,digital watermarking is becoming an ef- ficient method for protecting the intellectual property rights of digital products.For the copyright protection of digital video,a video watermarking algorithm based on 3D integer wavelet transform is proposed in this paper.The first step in this watermarking algorithm consists of breaking the video sequence into scenes.Then,3D integer wavelet trans- form is performed on the video scene.The watermark is embedded in the low frequency wavelet coefficients using mean quantization.The watermark can be extracted without the original digital video signal.The proposed algorithm is simple and efficient.Experimental results show that the proposed scheme can efficiently resist MPEG lossy com- pression and temporal de-synchronization attacks as frame dropping,frame insertion.
