Steganography & tools used for Steganography

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. Steganography is not only valid for images but it is valid for any digital media such as images, audio files, video files, and text files etc.This paper discusses the concepts behind steganography by exploring firstly what it is and how it has been used throughout in various aspects and Basics of Modern Steganography. This is followed by technical discussions on how it works and what methods and tools are used in stegnography. The paper explores the relationship with cryptography and how the two technologies differ. Finally, the future scope & conclusion presents 'The Right Way' to use steganography as a means of concealing information and the pitfalls to be wary of by outlining key points to consider when using steganography.
