Research On Communication Method Of Audio Information Hiding

With the rapid development of computer network, the problem of information security of communication system reveals itself. Information hiding technology has opened up a new way for secure transmission of information, which can guarantee security of communication. So the information hiding technology has become the focus of research in the field of information security.Firstly, the paper compares advantages and disadvantages of present algorithm, and on the basis of the present algorithm, the paper proposes the algorithm based on chaos sequence and error correction coding theory. The algorithm can guarantee both security and robustness when the information is attacked; Secondly, the paper proposes synchronization information hiding algorithm in DWT domain, which searches the synchronization code to locate the position of secret information before recovering the secret information; Finally, according to the characteristics of dual-channel audio signal, the paper proposes the information hiding algorithm of dual-channel audio signal.The experimental results show that the algorithm proposed has better security and robustness when the audio signal is attacked by noise addition, low-pass filter, resample, shearing and so on.
