Information-Theoretic Analysis of Security in Side-Informed Data Hiding
Abstract. In this paper a novel theoretical security analysis will be presented for data hiding methods with side-information, based on Costa’s dirty paper scheme. We quantify the information about the secret key that leaks from the observation of watermarked signals, using the mutual information as analytic tool for providing a fair comparison between the original Costa’s scheme, Distortion Compensated - Dither Modulation and Spread Spectrum.
