Many tools and methods for steganalysis are prevalent in the research field. While no technique is 100% effective, combining multiple techniques is common practice. Techniques reliant on the same basis are often found to be less computationally efficient when used in combination as opposed to the combined use of techniques in separate categories. It is the goal of this paper to present many of the foundational techniques, explore their strengths and weaknesses, categorize the techniques, and present further theories on the combinational effectiveness of techniques within and outside of those categories.
