Abstract

The huge advancement of wireless and versatile system as of recent years leads to some security concerns caused by increasing capacity of the networks and the large margin of the multi-media data. Different techniques such as cryptography, steganography and watermarking have been introduced. Among these techniques Steganography is a popular field in communication engineering because of its wide range of applications. In this paper, we introduce a novel, principled methodology of audio steganography. Audio steganography is a technique for embedding secret information in an audio signal. We propose Daubechies Wavelet based method to embed the encrypted information in an audio file. In the proposed system first the sender encrypts the secret message by IDEA algorithm and secondly encrypted secret message is embedded using Daubechies Wavelet families.
