Evaluation of the Validity of Image Watermarking
Wang Dao · Chinese Journal of Computers · 2003
This paper introduces the research methods of Steganalysis of Watermark techniques. By the comparison of several watermark benchmark tools, which are Stirmark, Checkmark and Optimark, authors discuss the security of watermark system, present an evaluation that satisfies the validity, and give a basic necessary condition to judge the validity of image watermarking. Authors also discuss the restrictive relations of robustness, payload and quality in watermark system. The public problems in watermark embedding techniques, which are brought by steganalysis and active attack, and the future directions in watermark embedding system are also discussed in the paper.
