Aimed to improve the detection efficiency of information-hiding blind detection system, the present study proposes an SADRID-I image steganalysis algorithm that is based on improved differential matrix, according to the high dimensions and correlation of image features. Using attribute significance and differential matrix that stems from rough sets theory, the algorithm can implement D attributes...
For improving the detection efficiency of hidden information blind detection system, an improved hidden information detection method based rough set theory is proposed against the high dimension of statistical features and high relevance about images. First, an improved general steganalysis system framework is proposed with practical method and steps; second, the Algorithm based on the rough set theory...
In this paper, a blind steganalytic scheme is proposed to effectively detect JPEG steganography. Nine statistical models are constructed from the DCT and decompressed spatial domain for a JPEG image. By calculating the histogram characteristic function (HCF) and the center of mass (COM), we measure the energy distribution of each model as one part of our feature set. Moreover, for each model constructed...
