A Comparative Study of Steganography Techniques: A Review

Abstract

Steganography and Digital Watermarking are two methods of information concealment in which the context can be interpreted as keeping the information hidden or making it subtle. Steganography is a means of disguising an information so that only the person(s) who placed it are aware of its existence. Onthe other hand digitalwatermarking is the technique of inserting a symbol of some form into a media file to differentiate it from others. Security authenticationis intended to be permanent, and it is applied by a process that involves changes to the media file. Other parties may be able to see or hide digital watermarking in plain sight. In this paper we are going to review the steganography techniques. This paper will do a whole comparativestudy of different steganography techniques also.
