A New Blind Steganalysis Method for JPEG Images
Xiang Li, Jianhua Li · 2008
In this paper, we proposed a new approach of steganalysis based on frequency features from DCT coefficients. This method does not require any training and can be widely used on JPEG images from various sources. We have applied our algorithm on images captured from digital camera,the Internet, and compressed images from lossless format. Experimental results show it works well on detecting popular DCT based steganography algorithms.
