摘　　要：在音频数字水印中,如何做到既能嵌入版权保护的图像水印,又能保持良好的透明性和鲁棒性仍是一项具有挑战的工作.针对这个问题,提出了一种基于Fibonacci-DWT-DCT-SVD的鲁棒性音频水印算法.借助Fibonacci和混沌序列为图像水印进行置乱加密;利用离散小波变换(DWT)、离散余弦变换(DCT)和奇异值分解(SVD)的特性,将加密后的图像水印嵌入到音频载体上.仿真实验结果表明,水印在经过噪音、滤波、回声、压缩等多种攻击后依然能提取出较完整的图像水印,说明该算法的水印鲁棒性强、透明性好.In audio digital watermarking,it is still a challenging task to embed copyright-protected image watermarks while maintaining good transparency and robustness.To solve this problem,this paper proposes a robust audio watermarking algorithm based on Fibonacci-DWT-DCT-SVD.With the help of Fibonacci and chaotic sequences,the image watermark is scrambled and encrypted;using the characteristics of discretewavelet transform(DWT),discrete cosine transform(DCT)and singular value decomposition(SVD),the encrypted image watermark is embedded on the audio carrier.The simulation experiment results showed that the watermark could still extract a more complete image watermark after various attacks such as noise,filtering,echo,compression,etc.,indicating that the algorithm has strong robustness and good transparency.
