Abstract:
Digital watermarking is used for the protection of the rights of the user. Copyright protection and information security are two most considered issues of digital data following the development of internet and computer network. In fact asan important solution for protection, watermarking technology is introduced. In this paper a hybrid DWT-SVD technique has been proposed to embed and extract a digital watermark into/from an image. Then, we pointed to experimental results (the values of PSNR, NCC & BER) to indicate the relationship between original watermark and the extracted one. We experiment the proposed method with various test images for the various attacks and compare our scheme with the previous method to show that the proposed method has excellent performance.
