A Steganography Implementation Based On DCT Algorithm By Using MATLAB GUI Function

Er. Yashpal Lather | Er. Megha Goyal

Abstract: Informally, steganography refers to the practice of hiding secret messages in communications over a public channel so that an eavesdropper (who listens to all communications) cannot even tell that a secret message is being sent. In contrast to the active literature proposing new concrete steganographic protocols and analysing Laws in existing protocols, there has been very little work on formalizing steganographic notions of security, and none giving complete, rigorous proofs of security in a satisfying model. This paper USED A image domain algorithms available for implementing Image Steganography. Covert communication is taking place by encrypting the password for information to be protected. The intended receiver will decrypt the information using that password.
