The past few years have seen an increasing interest in using images as cover media for Steganography communication. The basic structure of Steganography is made up of three components: cover image, message, and the key. The carrier can be a digital image; it is the object that will carry the hidden message. A key is used to decode/decipher/discover the hidden message. This can be anything from a password, a pattern, a black-code etc. In this paper we propose a new form of Steganography, Which deals with disadvantages of Simple LSB substitution and as well as symmetric cryptography algorithm called Blowfish algorithm.
