Abstract

A novel audio watermark algorithm based on stochastic resonance (SR) in the DWT and DCT domain is proposed. In this paper, the watermark is viewed as weak binary signals, and the DWT and DCT domain coefficients of audio carrier are randomly permuted to be an approximate white Gaussian noise. In decode-process, after the preprocessing of the audio to be decoded, the DWT and DCT domain coefficients are used as the input of the stochastic resonance system, by adjusting the parameter of the stochastic resonance processor, the detection of watermark can be achieved. Simulation results show that the watermarking scheme is robust, invisible and widely usable.
