DWTAS: A robust discrete wavelet transform approach towards audio steganography

Nowadays, hiding data under cover signal using the approach of steganography is the most important issue. The main goal of stenographic systems is to obtain secure and robust way to conceal secret data. In this article a new algorithm called DWTAS method for audio steganography and dual data hiding using discrete wavelet transformation is proposed. In dual data hiding, original message along with the keys are hidden in the entire data communication.
