Robust video watermarking algorithms based on Svd transform

Abstract

Video watermarking is a novel technology that has the ability to solve the problem of illegal digital video manipulation and distribution. In video watermarking, the copyright bits are embedded into video bit streams. This paper proposes two effective, robust and indiscernible video watermarking algorithms. Both the algorithms of video watermarking are based on algebraic transform of Singular Value Decomposition (SVD). In the first algorithm, watermark information bits are embedded in the SVD-transformed video in a diagonal-wise fashion, and in the second algorithm the watermarked bits are embedded in a block-wise fashion. The performance of both the algorithms is performed in lines of imperceptibility, robustness and data payload. Similar results have been achieved with both the algorithms. The only variation in their performance was found in the form of robustness and data payload. The first proposed algorithm attained better robustness results. While the second proposed algorithm attained higher data payload.
