摘要：This paper proposes a forensic method for identifying whether an image was previously compressed by JPEG. Though some methods have already been proposed for this purpose, Stamm and Lius anti-forensic method disables the detection capabilities of these methods. After analyzing the anti-forensics method, we propose to use the decimal histogram of the coefficients to distinguish the never-compressed images from the previously compressed; even the compressed image is anti-forensically processed. Experimental results show that this method has a good forensic capability.
