An Empirical Analysis of RS Steganalysis

Steganography is the science of hiding messages within some cover media.The intent is usually covert communication, but steganography is equally used for digital watermarking of media. Messages can be hidden in any media. Typical media include digital images, sound, and video. Steganalysis is the science of detecting the presence of hidden messages in media. Most steganalysis techniques search for artifacts created by the message hiding process. A simple and commonly-used steganograpy technique is LSB steganography where the least-significant bits (LSB) of data values in a media file are altered to hide a message. There are also a number of published steganalysis techniques for LSB steganography. This paper presents an empirical analysis of an LSB steganalysis technique called the RS steganlysis.
