Different Method Used in Pixel Value Differencing Algorithm
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 3
Abstract
Steganography is the art of hiding information inside a multimedia. The basic idea is to hide data inside carrier medium such as text, image, audio, video and networks in such a way that attacker cannot detect it. Image steganography is the major part of steganography which is divided into spatial and frequencydomains. Pixel value differencing is one of the spatial domain techniques. In this paper, we would review various pixel value differencing steganography techniques and also the changes in these techniques. This paper concludes with the need of better steganography techniques for color images and edge based images.
