A Robust Blind Video Watermarking Scheme Based On Discrete Wavelet Transform And Singular Value Decomposition

The outgrowth in technological world has massively promoted to information fraud and misappropriation by the ease of multimedia data content regeneration and modification. Consequently, security of digital media is considered among the biggest issues in multimedia services. Watermarking, consisting in hiding a signature known as watermark in a host signal, is one of the potential solutions used purposely for media security and authentication. In this paper, we propose a robust video watermarking scheme using Discrete Wavelet Transform and Singular Value Decomposition. We embed the watermark into the mid frequency sub-bands based on an additive method. The extraction process operates following a blind detection algorithm. Several attacks are applied and different performance metrics are computed to assess the robustness and the imperceptibility of the proposed watermarking. The results reveal that the proposed scheme is robust against different attacks and achieves a good level of imperceptibility.
