Watermarking systems are analyzed as a game between an information hider and a decoder on the one hand, and an attacker on the other hand. It is assumed that the attacker is informed of the hiding strategy taken by the information hider and the decoder, while they are uninformed of the attacking scheme. A single-letter expression for the capacity is found under the assumption that the covertext is drawn from a memoryless stationary source and its realization (side information) is available only at the encoder (public game).
