Role of Soft Computing Techniques in Improving the Strength of Steganographic Systems

In recent times steganographic systems that deal with concealing of secret data inside images have gained much attention. Robustness, capacity of embedding and imperceptibility are the major issues concerning embedding of secret data inside a cover. This paper analyses the recent advancements in this field by combining the soft computing techniques with steganographic algorithms for increasing the robustness, capacity and imperceptibility of the images used for embedding.
