摘要
对掩密分析技术的研究可以提高和完善信息隐藏技术,保护国家机密、商业机密以及个人隐私不受侵犯,具有现实的研究意义。文章介绍了掩密技术及掩密分析技术,针对掩密分析技术在图像掩密中的应用,分类讨论了各种图像掩密分析算法,并对各种算法进行综合分析和比较。进一步,文章对该领域今后的发展趋势和研究方向发表了看法。
Research on steganalysis helps improve steganography techniques and protect national and business classified information and personal privacy. Therefore, it is practically significant. Steganography and steganalysis are introduced in the paper. For the application of steganalysis in image, several steganalysis algorithms based on (Least Significant Bit Insertion) LSB in image are discussed, and analysis and comparison are made among these algorithms. In the end, the developing trend and research directions in this field are mentioned here.
