Combating Anti-forensics of Jpeg Compression
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.
