A New Robust and Secure Approach to SVD-3 Level DWT Video Watermarking

Digital watermarking is used to protect digital content such as images, audio and videos that have been tampered maliciously and with higher accuracy. Digital video watermarking is a new and merging area of research to exploit different ways in order to prohibit illegal replication and exploitation of digital contents. In this paper, to maintain the quality of video and to ensure the ownership we propose a new SVD-3 Level DWT watermarking embedding technique. Singular value decomposition (SVD) is an important transform technique in robust digital watermarking. We apply the 3 level DWT and SVD on selected frames and embed the watermark into randomly selected frames with the help of secret key to authenticate the video by considering the video quality, robustness and video imperceptibility.
