New Steganalysis Approach for JPEG Image Steganography using F5 Algorithm
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 7
Abstract
Recently, there has been a lot of interest in the fields of Steganography and Steganalysis. Steganography involves hiding information in a cover (carrier) media to obtain the stego media, in such a way that the cover media is perceived not to have any embedded message for its unintended recipients. JPEG is a popular cover image format used in Steganography. Two well-known Steganography algorithms for hiding secret messages in JPEG images are: the F5 algorithm and Outguess algorithm. Steganalysis is the mechanism of detecting the presence of hidden information in the stego media and it can lead to the prevention of disastrous security incidents. In this paper, we present a steganalytic method that can reliably detect presence of messages hidden in JPEG images using the steganographic algorithm F5. The key element of the method is estimation of the cover-image histogram from the stego-image. By cropping JPEG image more times along the oblique direction, this algorithm can deal effectively with abnormal data and get better results.
