Experimental Analysis and Comparison of LSB substitution and LSB Matching Method of Information Security
Steganography is an art of covert communications. Its core function is to conceal the occurrence of communication over a civic channel. Hiding the occurrence of communication can be done by embedding a secret message into cover medium which no one else than the correspondent and the addressee can expect and steganalysis is the art and science of recognizing a clandestine communication. The purpose of this paper is the analysis of chosen technique experimentally, evaluate the technique, compare results on literature and give direction on what can be done for new and better approach of steganography and steganalysis.
