Abstract
A method of encryption for embedding a meaningful gray image in the frequency domains of an audio signal is described. Chaotic sequence based on logistic map is adopted to improve the security of the proposed watermarking scheme by quantizing wavelet packet coefficients of audio samples. Simulations under various conditions are given to verify the effectiveness of the audio watermarking scheme. The results show the proposed scheme is secure, and the watermark is imperceptible and robust against audio signal processing attacks such as noising, low filtering, resampling and compressing.
