Abstract: Today’s Computer world ensures security, integrity, confidentiality of the organization’s data to a very large extend. 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. 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.
Keywords: Spatial Domain, Frequency Domain, Patchwork, Spread Spectrum.
