An Active Steganalysis Method of Block-DCT Image Information Hiding

摘要：

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 improve the steganalysis the efficiency and the accuracy, but also improve the reliability of estimated message length.
