An Evaluation Scheme for Steganalysis-proof Ability of Steganographic Algorithms

With the development of steganalysis, steganalysis- proof ability of steganography is becoming more and more important. The evaluation for steganalysis-proof ability of steganographic algorithms can provide theoretical foundation and promote the development of steganalysis-proof ability of steganographic algorithms. This paper proposes an evaluation scheme for steganalysis-proof ability of steganographic algorithms. According to the intensity of steganalysis, this scheme classifies the steganalysis-proof ability of steganographic algorithms into three grades from weakness to strongness. The proof schemes to the three grades are given in this paper, which thus can be used to evidently prove the grade of steganalysis-proof ability of any steganographic algorithms. The evaluation scheme has a better performance of evaluating the steganalysis-proof ability of a steganographic algorithm, and can provide a quantitative evaluation criterion for steganalysis-proof ability of steganographic algorithms.
