Secret data when transmitted over the network must be protected from the illegal copy, modification or destruction by the malicious user. Audio steganography is a technique that provides a platform for secure transmission of secret data over the internet. In audio steganography, the secret data is transmitted with audio signal as the carrier. This paper proposes a high capacity and security audio steganography technique to hide secret audio signal. In this technique, in lieu to ensconcing the secret information as a whole in the cover object a key corresponding to the secret information is produced and hidden imperceptibly in the cover signal. The key is used to retrieve the secret information. To generate the key and to conceal it in the cover, integer wavelet transform (IWT) is used. The performance metrics obtained are well above the required level of HAS, indicating good security and robustness of the stego system.
