Steganographic algorithm based on randomization of DCT kernel

Abstract

Calibration attack is one of the most important attacks specially on JPEG domain steganography. Prediction of cover image statistics from its stego image is an important requirement in calibration based attacks. Domain separation techniques are used as a counter measures against such attacks because they make the cover image prediction process rather… (More)
