Robust method of digital image watermarking using SVD transform on DWT coefficients with optimal block

Over the last few years, development of internet and technology of media, the protection of copyright have become very important. To protect multimedia data against illegal copying and transferring, the insertion of a signal (digital signature, watermark) has become a duty without modifying quality of the original image, the goal of this operation is to identify the owner and protect his intellectual property. Digital watermarking has been proposed as a solution to solving the copyright problem by introducing invisible data (watermark) into original image. In this paper, we propose a study of digital images watermarking. This study is achieved by inserting watermark in different coefficients of DWT (LH, HL, HH) using SVD transform by searching the optimal block that have the maximum entropy which can be used to insert the watermark in original image. The experimental results show the different results of PSNR for each coefficient of DWT and the robustness against most attacks.
