We evaluate the statistical visibility of information hiding algorithms based on the coefficient of kurtosis , differential entropy , goodness of fit test and kullback entropy . on these bases some methodologies are suggested to defend against statistical steganalysis 重點(diǎn)研究了含密序列統(tǒng)計可見性的定量評估,提出了基于峰度系數(shù)和微分墑的偏態(tài)評估、基于擬和優(yōu)度檢驗(yàn)的統(tǒng)計可見性評估和基于鑒別信息的統(tǒng)計可見性評估。
