There are many image steganalysis methods that detect presence of hidden data into the stegoimages generated by LSB steganography. However if the stegoimages is generated by JPEG steganography, these methods show inefficiency of the detection of hidden data. The JPEG steganography is a data hiding technique that performs data hiding in DCT domains. In the steganalysis side, any information about the stegoimage is not available; therefore many steganalisis methods for different types of stegoimages must be combined to generate an efficient steganalisis methodology. In this paper a reliable steganalysis method for JPEG steganography is presented, this steganalysis method later can be added into global steganalysis methodology. The evaluation of steganalysis methods is realized in terms of false negative and false positive error rates.
