Audio Information Hiding Algorithm Based on MH Public Key
Zhao Yan-qin · Computer and Modernization · 2009
Secret audio message has to experience all kinds of attacks during transporting.The 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.Combing MH public key and hamming coding,the algorithm not only encrypts the hiding information but also corrects the error coding.It also has strong anti-disturbance ability against noise,compression and filter.
