摘要: 音频信息隐藏技术已成为近年来的研究热点之一,将混沌理论引入到音频水印系统的研究中,设计了一种将一段音频作为水印,利用混沌序列选择部分原始音频信号作为载体,将混沌加密后的音频水印嵌入到载体的小波系数中的音频信息隐藏方法。实验表明,水印具有很强的安全性和鲁棒性。

Abstract: Audio information hiding technology is studied recent years.In this paper,the technology of embedding the audio signal based on chaotic encryption is researched.A short audio watermarking encrypted by a chaotic sequence could be embedded in the original signal wavelet domain in the algorithm.The experimental results show that using chaos sequences to audio information hiding is of high security and robustness.

Key words: audio watermarking, chaotic encryption, chaotic sequences, DWT, security, robustness
