军事通信中基于DCT域直流分量的音频数字水印技术研究
Study on audio digital watermarking technology based on DC component of DCT domain in military communication
摘要
Abstract
It is necessary to ensure to give first priority to the information absolute security in military communication. At present,the field communication of Chinese army mainly relies on the wireless communication means,and the identity recognition of the both communication sides is the basic premise to ensure the wireless communication security of battlefield. On the basis of active-service communication equipment,a DCT based scheme of embedding watermark in DC component and extracting the watermark from the DC component is designed to improve the communication security of battlefield,which can provide the safe-guard for identity recognition. With Matlab simulation,this technology is compared with prevalent discrete wavelet transform (DWT)technology in the aspects of imperceptibility,extraction credibility and anti-interference. The results show that the tech-nology is suitable for the identity recognition in the battlefield communication environment.关键词
