Digital Video Watermarking Using Motion Detection and Singular Value Decomposition

Various digital watermarking techniques have been proposed in recent years for the purpose of protection of intellectual property rights of the creators of multimedia data, such as digital video. In order to achieve copyright protection of digital video we have adopted an imperceptible video watermarking approach based on Motion Detection and Singular Value Decomposition. Motion detection using temporal difference is used to identify the motion regions within a video frame where a watermark can be effectively embedded to ensure imperceptibility of the watermark. The unique properties of the singular values of an image, in this case the individual motion regions within the video frames, are utilized to enhance the robustness of watermarking and make it non-invertible. The resultant watermarked video is then tested for its robustness against attacks for watermark degradation and removal.
