Abstract

Digital watermarking is an efficient and promising approach to protect intellectual property rights of digital media. In this paper, a new scheme of robust audio watermarking based on Fractional Fourier transform (FRFT) domain for copyright protection is proposed, which utilizes the idea that FRFT can be considered as a rotation in time-frequency joint domain. Test results for imperceptibility of the watermark and its performance of detection are presented. The simulation study shows that the watermark performance is better than the classical spread spectrum audio watermarking scheme.
