Abstract: This paper proposes a new idea of audio information hiding which makes use of chaos’ characteristic that is extreme sensitive to the initial value.In the algorithm a chaos sequence chooses the wavelet-base，while another chaos sequence decides location of hiding.It is a blind detection algorithm while distilling secret data doesn’t require carrying data.The algorithm takes full advantage of the traditional secure communication and information hiding.It has good secutity by experiment proving.

Key words: wavelet transform, chaos, information hiding, security communication
