A Novel Analysis Method of Information Hiding

The research on information hiding theory is drawing more and more enthusiasm in recent times. This paper tries to solve theoretical problems about information hiding using vector space methods. Firstly, we project information hiding system into vector space. Then we give the significations of imperceptibility, embedding intensity, attack intensity and robustness in multi-dimension space. Subsequently, the existence theorem of information hiding system is given and proved. Finally the upper bound of capacity is given. All of them provide a novel method to the analysis and development of information hiding system.
