Abstract: A digital image scrambling method based on the Fibonacci numbers is presented in [Zou J. et al. 2004]. A novel audio watermarking method based on Fibonacci numbers is given in this paper. The experiment results show that the algorithm has better robust than the traditional phase watermark algorithm. Based on the property of uniformity of the corresponding Fibonacci transformation, the watermarking method has the following advantages: (1) Encoding and decoding are very simple and they can be applied in real-time situations. (2) The algorithm can endure severe attacks such as extreme noise levels, very high loss in its data or data packets, or m3 compression.
