Abstract
  The aim of image steganalysis is to detect the presence of hidden messages in stego images. We propose a blind image steganalysis method in Contourlet domain and then show that the embedding process changes statistics of Contourlet coefficients. The suspicious image is transformed into Contourlet space, ...  Read More

Eigenvalues-based LSB steganalysis

F. Farhat; A. Diyanat; Sh. Ghaemmaghami; M. R. Aref

Volume 4, Issue 2 , July 2012, , Pages 97-106

https://doi.org/10.22042/isecure.2013.4.2.1

Abstract
  So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through ...  Read More
