RT Journal Article ID 36da594b1cabf28d A1 Nikitenko, Lyubov L. T1 Application of the Extended χ2-Criterion for Embedded Information Detecting JF Journal of Automation and Information Sciences JO JAI(S) YR 2015 FD 2015-05-22 VO 47 IS 4 SP 36 OP 42 K1 embedded information detecting K1 extended -criterion K1 JPEG images K1 estimates of the stego histogram K1 embedding rate K1 empty container histogram AB 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.
