Abstract :
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
