Survey and Analysis of Edge Based Steganographic Techniques

摘要

The main goal of steganography is undetectablity. Towards this goal edge based adaptive techniques of steganography are used, due to the fact that edge area is less sensitive to human visual system. In this paper we have presented the prominent techniques for finding edges and their advantages and disadvantages. Exhaustive literature survey has been done to find which technique is better in terms of embedding rate and Steganalysis, what are the drawbacks of these techniques. This paper concludes with some recommendations and advocates for constructing an edge adaptive technique and presenting results.
