Abstract
An information-theoretic model for image watermarking and data
hiding systems is presented. The fundamental capacity limits of these
systems are determined by the statistical model used for the host image,
by the distortion constraints on the data hider and the attacker, and by
the information available to the data hider, to the attacker, and to the
decoder. We consider wavelet statistical models for images and compute
the data hiding capacity for compressed and uncompressed host image
sources. Closed form expressions are obtained under sparse-model
approximations
