摘　　要：信息隐藏是信息安全和多媒体信号处理领域一个非常年轻但又发展迅速的研究方向。隐写术和隐写分析是信息隐藏的重要研究内容。介绍隐写分析的原理,给出隐写分析方法的四个评价指标,从隐写分析类型的角度给出图像隐写分析通用原型系统。将国内外隐写分析研究方法分为专用和通用隐写分析两类,分别介绍其研究现状,对每类中典型的隐写分析方法进行评价,并对隐写分析中存在的3个主要问题进行讨论,指出隐写分析未来的发展方向,展望隐写分析的前景。Information hiding has become the forefront of information security and multimedia image processing. Steganography and steganalysis are important research content of information hiding. Steganalysis principle, gives four estimated values for steganalysis method and general prototype system of image steganalysis based on types of steganalysis from the view of warden are introduced. Methods of steganalysis research home and abroad are divided into two types,special and universal steganalysis. Research actuality of either type is presented and representative methods of either type are evaluated. Three main problems existed in steganalysis are discussed, future direction in steganalysis development is pointed out, and prospect of steganalysis is expected.
