An active steganalysis method is proposed based on HMT (hiding Morkov tree) model and independence component analysis (ICA) methods, aimed at the block-DCT coefficients steganography in this paper (here we assume only one copy of stego message image is supplied). The simulation experiments in Matlab7.0 show that the active steganalysis method can not only(More)
Advanced video coding standards have become widely deployed in numerous products, such as multimedia service, broadcasting, mobile television, video conferences, surveillance systems and so on. New compression techniques are gradually included in video coding standards so that a 50% compression rate reduction is achievable every ten years. However,(More)
