Steganography is an emerging area which is used for secured data transmission over any public media. Steganography is a process that involves hiding a message in an appropriate carrier like image or audio. It is of Greek origin and means "Covered or hidden writing". The carrier can be sent to a receiver without anyone except the authenticated receiver knowing the existence of this information. In this paper, a specific image based steganography technique for communicating information more securely between two locations is proposed. The author incorporated the idea of secret key and password security features for authentication at both ends in order to achieve high level of security.
