چکیده
In this research work adopted the frequency domain watermarking scheme which is embedded using discrete wavelet transform (DWT) and singular value decomposition (SVD). By singular values factoring it represent smaller set of values and it can preserve constructive feature of an original image. After that, apply discrete wavelet transform in decomposed in low frequency sub-band on both images to improve the value PSNR. The MSE, PSNR and computation time performance parameters are taken to measure the efficiency of the propose method. The simulated experimentation is done in MATLAB and the simulation results of propose method (DWT-SVD) gives improved results than the existing method (DWT).

Digital watermarking is nothing but the technology in which there is embedding of various information in digital content which we have to protect from illegal copying. This embedded information to protect the data is embedded as watermark. In digital watermarking, a watermark is embedded into a cover image in such a way that the resulting watermarked signal is robust to certain distortion cause...
