Introduction Statistical steganalysis detects hidden content by discovering distortions in the statistical properties of the stego medium. Iterative process. Improved embedding algorithms requires better steganalysis. Improved steganalysis leads to better embedding algorithms. Besides its inherent technical interest, steganography has become the subject of intense public and press scrutiny. Reportedly, steganography is being used by criminals to communicate plans in secret on the Internet. We developed a steganography detection framework to show how to apply steganalysis in practice.
