In the recent years, digital watermarking is used for copyright protection and authentication. In this paper, a new dual watermarking scheme based on DWT-SVD is presented to improve the robustness and protection. Both discrete wavelet transform (DWT) and singular value decomposition (SVD) have been used as a mathematical tool to embed watermark in the image. In the proposed technique, two watermarks are embedded in the host image. First watermark is called primary watermark, which is a gray… CONTINUE READING
