Abstract : Watermarking technology aims to solve the multimedia copyright protection problems in particular on computer networks such as Internet. The technology must show proof of ownership with a very high degree of confidence and demonstrate a strong resistance against the hackers distortion like the noising, compression, filltering. The approach proposed in this paper consists of a new image watermarks embedding / extraction algorithm based on the singular value decomposition SVD. The results obtained show that our algorithm resists perfectly against the hackers attacks which demonstrates the robustness of the proposed approach.
