要約

An algorithm for organization of attacks on stegosystems, incorporating data into JPEG format images, is presented. Specific features of the methods are explained using as examples the algorithm F5, for which data on the accuracy of evaluation of the message size using test images are given. Limitations of the proposed approach are identified; it is shown how to avoid such limitations and to obtain accurate results of detection in each case. The condition, which must be met by high-capacity stegalgorithms working with JPEG files, is formulated.
