We propose a simple method for increasing the reliability of detection of LSB replacementsteganography. RS Steganalysis Method (RSM), Sample Pair Method (SPM), and Least Square Method(LSM) are three of the most reliable steganalysis methods in the literature for LSB replacementsteganography on digital images in spatial domain. However all these methods are prone to error. Wepropose a simple method to identify images which give very accurate results and images which givehighly inaccurate results by these methods. The novelty of our method is that it does not require anyknowledge about the cover images as the image classification is done based on certain statisticalproperties of the image, which are invariant with embedding. Thus it helps the steganalyst in attaching alevel of confidence to the estimation he makes and thereby increasing the reliability of steganalysis ofdigital images. It also helps to choose between images for more secure LSB replacement steganography. |
