The problem of efficient data hiding robust to lossy compression is divided into two subproblems. First is to maximize the resource - which is the permitted distortion of images. The second is the efficient use of the resource by means of sophisticated signaling techniques. We conclude that a good solution to the first problem is choosing magnitude discrete Fourier transform as the domain in which the message signal is embedded. For the signaling method we use a sophisticated signaling technique, using periodic functions to tile the space with signal constellations.
