Abstract :
In this paper we discuss the essence of information transmission in digital watermarking system and the dissymmetric digital watermarking framework lived on media content communication. Then we propose a universal entropy masking model for watermarking embedding algorithm to keep the balance between watermarks´ imperceptibility and its robustness. Also we conclude from the experiments that a suitable domain of entropy calculation will result in optimal watermarking performance.
