摘要：Video Watermarking is the technique by which some information is inserted in the video which can be extracted later. It provides protection against any kind of illegal manipulation by third party. In this paper , a non -blind watermarking scheme is proposed which is based on the combination of Discrete Wavelet Transform,(DWT), Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD).The watermark is embedded in the mosaic formed from the frames of the video by modifying the DCT coefficients of LL1 (low frequency sub-band obtained by applying 1- level DWT on the mosaic) followed by diagonal based modification of singular value matrix which is obtained by SVD decomposition of LL2 (low frequency sub-band obtained by applying 2-level DWT on the modified LL1).The experimental values of PSNR, Correlation Factor show that the above proposed scheme is imperceptible, secure and robust against various types of attacks.
