SINOPSIS

One of the steganoanalysis methods − the extended χ2-criterion, applied for detection of the information, embedded into the least significant bits of the JPEG images, is considered. The method is based on the comparison with a user-defined threshold of the averaged value of the χ2-function. As a result of calculation, the estimates of the stego histogram and value of the χ2-function as functions of the embedding rate and empty container histogram are obtained.
