LSB steganographic detection using compressive sensing

Abstract

People have always been using several techniques in order to protect their privacy. For centuries, steganography has been used, but only in the last decades the proper mathematical background has been developed. Due technological advances, steganography has found many applications, with most important the protection of digital assets through DRM. This work proposes a new detection method of steganographic content through compressive sensing. The proposed method is a probabilistic filter that can detect steganographic content in images with increased probability, if this is made with the LSB method, after applying a filter with compressive sensing technique. © Springer-Verlag Berlin Heidelberg 2011.
