Abstract

This paper introduces a steganographic algorithm that generates a stego image based on a model describing plausible values for the pixels of that image. The model is established by analyzing a number of realizations of the cover image. The main contribution of the approach is that the model describes dependencies on adjacent pixels. Consequently, embedding according to the suggested approach considers image structures. The general approach includes parameters that influence the achievable security of embedding. Extensive practical tests using selected steganalytical methods illustrate the improvements of security compared to additive steganography and point out reasonable settings for the parameters.
