An experimental analysis of feature based blind steganalysis techniques

Abstract

Steganalysis is the finding of the hidden information in an image. Steganalysis is named as blind steganalysis if hidden data is searched without any restriction to any specific algorithm. Many research works has been done in this area for more than one decade. The detection algorithms are software tools mostly developed using MATLAB and C-language codes. Among the various approaches, feature extraction and classification based blind steganalysis is proved to be significant. This paper presents few well-known approaches among them.
