| Abstract: | Purposes—To design and implement a practical semi-fragile audio watermarking sys-tem.Methods—Based on the design language of MATLAB program and from the perspective of soft-ware 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 watermark-ing 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 w atermarking system. |
