In the third part, the essences of steganography and disadvanges of common visual perception evaluation, such as psnr and wpsnr are studied. based on analysis local error that is introduced by embedding information, combining hvs, three objective perception evaluation method for steganography performance are proposed, which are based on human visual systems and local statistic error distribution respectively. in the steganalysis part, a steganography security statistic attack model and methods for some steganography methods are presented
在信息隱藏的性能評價方面，研究了常用的峰值信噪比，加權峰值信噪比等前人提出的感知性能評價準則，指出針對信息隱藏的性能評價不能單純從視覺特性出發，提出從信息隱藏的數據特性和感知特性出發，結合局部特性來考察失真誤差的變化的思想，並據此提出基於局部區域誤差統計分佈和視覺掩模方法評價信息隱藏性能的方法。
