Steganography ABSTRACT

Steganography is the practice of representing information within another message or physical object, in such a manner that the presence of the information is not evident to human inspection. In computing contexts, a text message is concealed within another audio, video, text or image file. The word “Steganography” originates from the Greek word “steganographia” where “stegano” means “covered or concealed” and “graphy” means “writing”.

The advantages of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages, no matter how unbreakable they are, arouse interest and many in themselves are incriminating in countries in which encryption is illegal. Whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent and its contents.

Through the concept of steganography, this project wishes to hide the text message in the cover files like audio, video, text, image files. The purpose in doing so is to create a fine multi purpose Steganography Tool to increase the security of confidential messages across a network when only sender and receiver knows the trick behind the steganographic message.
