Implementing Multiple Security for Audio Steganography

Abstract

Cryptography is being used by organization in order to transmit a secret message successfully without being caught up by the enemies. Cryptography has evolved rapidly from the ancient times to the modern world. The information which is being transmitted from one place to another is vulnerable to various types of active and passive attacks. Therefore, the security of the information is one of the most challenging aspects of communication in today’ time. Steganography is the process of hiding information which are need to be transferred on insure transmission medium (e.g., Internet) so that no one except sender or receiver can know the very existence of information. As the message is not visible so it does not get any attention of unauthorized users which safeguard the secret message. A hybrid method for audio steganography (using modified Direct Sequence Spread spectrum) and cryptography (using advanced random permutation with multiple key applications) has been proposed in this paper.
