Abstract

In this paper, we investigate the calibration technique used in steganalysis of LSB matching. Instead of working on the original image, we propose to calculate the calibration-based detectors (e.g. Calibrated HCF COM) on the difference image, which is defined as the difference of the adjacent pixels of an image. The theoretical reliability of the new detectors is carefully studied. Moreover, several practical observations for enhancing the detectability are also given. The extensive experimental results clearly illustrate that the new detectors outperform the previous. Indeed, the new ones perform well even when the embedding rate is low.
