| 摘 要： | 分析Cachin的基于假设检验理论的安全性模型,指出在安全性建模中应该对感知特征和统计特征同时进行约束。通过限制条件转移概率的取值约束载体感知特征和统计特征的变化,建立信息隐藏理论安全性模型。结合数字图像的具体特征进行图像载体隐藏安全性建模,给出2种图像载体隐藏安全性建模方法,得出信息隐藏理论安全的充要条件。

| Abstract: | This paper analyzes the theoretical-security model based on the theory of hypothesis testing proposed by Cachin, pointes out both visual and statistical characteristics should be restricted in the process of information-hiding theoretical-security modeling. An innovative security model is created in the way to restrict the variation of both visual and statistical characteristics by confining the value of conditional transferred probability. The security model of information-hiding based on digital images is... |
