Three Layer Data Hiding Using Audio Steganography

Abstract: This paper is about the study of cryptographic and steganography techniques and provides the approach of security with the combination of these techniques. The transmission of information need to be secure over the network and confidentiality of information is main aspect for the critical information. This paper proposed the multiple layer approach for security of information which includes the hashing, cryptographic steps and steganography techniques for encryption and hiding of data. For more security, the LSB technique has been considered with audio file for hiding of encrypted information. Hashing for maintain the confidentiality of information, cryptographic for encryption and then hiding in audio. Audio steganography requires a text or audio secret message to be embedded within a cover audio message. DES cryptographic algorithm has been used with Hashing algorithm. This Paper provides a new way of securing the information to avoid hassle in transmission over network.
