摘要

隐写术被表述为信息隐藏者和攻击者之间的游戏。该公式中的代价函数是给定主机数据集的攻击通道输入和输出之间的条件互信息。最优的信息隐藏和攻击策略对应于最优的信道编码和数据压缩策略。

Information theoretic analysis of steganography

Steganography is formulated as a game played between an information hider and an attacker. The cost function in this formulation is a conditional mutual information between the input and output of the attack channel given the host data set. Optimal information hiding and attack strategies are shown to correspond to optimal channel coding and data compression strategies.
