Abstract

Abstract: Secret audio message has to experience all kinds of attacks during transporting. This paper presents a steganography algorithm with strong robustness. It embeds a speech as the secret message into original audio signal, and transmits the secret message in the public channel. The algorithm makes use of Human Auditory System (HAS) characteristics and embeds secret message in the wavelet domain. With knapsack publickey, the algorithm not only encrypts the hiding information but also encrypting the information. It also has strong antidisturbance ability against noise, compression and filter.

Key words: knapsack publickey, wavelet transform, information hiding
