A Survey on Steganography and Steganalysis Techniques in Secret Communication

Abstract

This paper presents a survey on classical steganographic algorithms and detection techniques (i.e.,
steganalysis techniques) along with their mathematical definitions. A little to no studies found that
tried to provide mathematical definitions of these algorithms. Wheras, mathematical definitions and
examples of different existing algorithms could help researchers to develop better understand how
previous algorithms and their limitations. In-depth understaning is important to improve existing and
develop new algorithms. Also, this paper presents a comparison chart of existing algorithms to show
advantages and disadvantages of each steganographic algorithm in terms of steganalysis or detection
techniques.
