ABSTRACT Digital multimedia content has progressively becoming an important issue because image watermarking is identified as a foremost technology used in copyright protection. The main requirement for image watermarking is its imperceptibility and robustness. To achieve these requirements, a new approach for image watermarking based on singular value decomposition (SVD) and discrete wavelet transform (DWT) is proposed in this paper. Modification of the appropriate sub-bands leads to a watermarking scheme which positively preserves the quality. The additional advantage of the proposed technique is security, imperceptability and its robustness against the most of common attacks. In this method, the singular values of DWT coefficients of B-plane are modified using different scaling factors to insert the singular values of watermark. The singular values of R, G, B planes of watermark are embedded into the three sub- bands LH, HL, HH of B-plane in host image. The proposed watermarking is realized by using MATLAB and evaluated by using performance metrics MSE, PSNR. Keywords:- Watermark, DWT, SVD, PSNR and MSE
