A New Steganalysis Approach Based on Both Complexity Estimate and Statistical Filter

The development of steganalysis technique becomes more and more important, because steganalysis could be used to detect the fact that terrorists are using steganography to hide their communication from law enforcement. In this paper, we study on the spatial nature difference between cover-images and stego-images, and present an effective approach used for steganography detection. The method we proposed is based on both statistical filter and estimate of bit-plane-complexity, and experimental results by the approach show that it could detect hiding fact more effectively, that is, reveal the facts that there is information embedded in the image.
