High Capacity Filter Based Steganography

Establishing hidden communication is an important subject of discussion that has gained substantial importance nowadays with the advancements in the era of the Internet. One of the methods introduced for accomplishing hidden communication is steganography. Steganography is an important area of research in recent years involving a number of applications. It is the science of embedding information into the cover image viz., text, video, and image (payload) without causing statistically significant modification to the cover image. In this paper we present an image based steganographic algorithm named as High Capacity Filter Based Steganography (HCFBS), that combines Least Significant Bit (LSB) method for data hiding, and the filtering techniques for image enhancement.
