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 difficult. Most of the algorithms in the past are based on randomization of embedding locations. In this paper, we propose a new domain separation technique which is based on randomization of DCT kernel matrix. A comprehensive set of experiments are done to validate that the proposed domain separation scheme performs better than the related existing schemes.
