Selection-channel-aware reverse JPEG compatibility for highly reliable steganalysis of JPEG Images

Abstract : This paper deeply studies the principle of the recent reverse JPEG compatibility attack [1]. This analysis allows us to cast the problem of hidden data detection in DCT coefficients within hypothesis testing theory. The optimal LR test, thought efficient, is rather computa-tionally expensive. Therefore, mild assumptions are used to simplify the detection problem dramatically and design a test that is simple yet extremely efficient and reliable. It is shown that the proposed detector is way more efficient than the original test [1], and allows highly reliable detection of data hidden within JPEG images.
