摘要
信息隐藏技术是最近兴起的信息安全领域的一个研究热点,其原理是利用载体中存在的冗余信息来隐藏秘密对象。隐写术和数字水印是信息隐藏的两个主要的技术分支。介绍了信息隐藏和隐藏分析近几年来的现状,总结了信息隐藏的几种典型算法和近几年来针对这些隐藏算法发表的多种隐藏分析方法。最后对这些分析方法做了简要的分析比较,并对信息隐藏的后续研究进行了简单的分析和展望。
Information hiding has become a hot interest area recently in the research of information security .It is to embed private messages inseemingly innocuous cover messages making use of the redundancy information.Steganography and digital watermarking are two main sub-disciplines of information hiding. It＇s introduced the actuality of the information hiding and steganalysis in recent years in this paper, summarized several typical algorithms of information hiding and various steganalysis method that published contrapose these algorithms mentioned above.Finally,a brief analysis and comparison was done to these steganalysis methods, and analysis and porspect the latter research to the information hiding.
