Most steganalysis today is signature based, corresponding to antivirus and intrusion detection methods. Anomaly based steganalysis systems are just beginning to emerge. Although matlab programming former systems are good and robust, matlab programming latter will be more bendy and better able to quickly reply to new steganography concepts. One kind of so called “blind steganography detection” distinguishes between clean and steganography images using records according to wavelet decomposition, or matlab programming exam of space, orientation, and scale across subsets of matlab programming larger image Farid 2001; Jackson et al. 2003. This form of statistical steganalysis is not restricted to image and audio files. Predators and Victims are mapped to motive assignments, and then matlab topic is selected in keeping with these motives. The goal of each and each predator has matlab multinomial distribution on topics, and every topic has matlab multinomial distribution on words. First, matlab programming motive assignments can be made separately for every word in matlab document. This model represents that a person can change motive during matlab programming exchange of matlab programming messages. Author Topic AT model has been prolonged by incorporating matlab new set of variables like authors as Predators and Victims, matlab programming motivation of an author. In this generative method for every message, matlab Predator, pd and matlab set of Victims, vd are followed.
