摘　　要：目的设计并实现一个实用的半脆弱音频水印系统。方法基于MATLAB程序设计语言,从软件设计的角度,根据半脆弱音频水印的功能需求分析,设计半脆弱音频水印算法,并应用MATLAB的GUI来设计水印系统。结果水印系统在一般音频信号处理中鲁棒性强,并能准确定位恶意篡改,体现出半脆弱水印的特性。结论 MATLAB语言在半脆弱音频水印系统的研究与设计中简便、高效。Purposes-To design and implement a practical semi-fragile audio watermarking system. Methods-Based on the design language of MATLAB program and from the perspective of software design, the semi-fragile audio watermark algorithm is designed according to the function require ment analysis, and MATLAB GUI is used to design watermarking system. Results-The watermarking system shows the characteristics of semi-fragile watermarking, because it has good robustness in normal audio signal processing and high accuracy for locating and alerting of the malicious tamper. Conclusions-The MATLAB language is simple and efficient for the research and design of semi-fragile audio watermarking system.
