A new scheme of watermarking in multi-resolution filed by 5/3 wavelet: Family signature combined with the adapted embedding strength.

Many studies are interested nowadays in the copyright of the multimedia data. In this framework, digital watermarking is a recent tool that offers some solutions. The new researches on this technique are mainly focalized on the tradeoff that exists between the insertion capacity, the imperceptibility and the robustness. The embedding function and the referencing mark have a great influence on the performance of the digital image watermarking. In this study, we use adaptive embedding strength in our insertion function which, improve the robustness and the imperceptibility of the digital watermarking. We replace, also, the referencing mark used in the classic scheme by a relative daughter mark. This new reference takes into consideration the inserted signature and the original image. This enhancement assures a better robustness. In this work, we combine those two approaches. We are interested by the non blind image watermarking applied on multi-resolution field by 5/3 wavelet
