Some design issues for robust data hiding systems

We explore the intricacies of the duality of data hiding and data compression to help develop optimal data hiding techniques for images, that can reasonably resist lossy compression. The problem of efficient data hiding is split into two sub-problems-one of maximizing the resource-which is the permitted distortion of images, and the other of efficient use of the resource by means of sophisticated signaling techniques. Various options for the solutions of the former problem are proposed and their advantages and disadvantages explored. An optimal data hiding scheme making "good" use of the resource, using sophisticated signaling techniques is proposed.
