Abstract :
The need for reversible or lossless watermarking methods has been highlighted to associate information with losslessly processed media or to enable their authentication. The paper first analyzes the specificity and the application scope of lossless watermarking methods. An original circular interpretation of a bijective transformation is then proposed to implement a method that fulfill all quality and functionality requirements
