In this paper, robust watermarking scheme has been proposed using FastHadamard transformation and singular value decomposition technique. This technique has an ability to embed or hide an entire image or pattern as a watermark directly into the original frames of the digital video sequence. As the quality of the digital media is to be preserved, the entire video sequence is not altered for embedding. Onlyfew frames are altered which is selected by pseudo random number generator. In order to reduce the computational complexity of the proposed algorithm,Fast Hadamard transformation is used. Theproposed algorithm is tested with rugby video sequence containing 209 frames and watermark of size 64x64 using MATLAB software. The experimental results show that our scheme is robust to most of the attacks and prevents the copy right of the digital media from the hackers. © Research India Publications.
