基于水印的军列监控信息隐匿传输系统研究

铁路军事运输对保密工作要求严格。将数字水印技术应用于铁路军事运输监控信息隐匿通信,在实现监控信息隐匿传输的过程中,通过对水印信息嵌入方法的改进,采用对信息嵌入位置进行置乱以及嵌入干扰数据,设计一种结合LSB与DCT算法的方式以提高水印信息的破解与提取难度。给出了系统实现的具体方案,并进行了实地测试与分析。通过实验验证了算法的有效性以及系统能够实现铁路军事运输监控信息的隐匿传输。

Research on Military Train Monitoring Information Hiding Transmission System Based on Watermarking

Military Railway Transportation is strict in confidentiality. In this paper,we applied the digital watermarking technology in Military Railway Transportation monitoring information hiding communication,in the process of realizing hidden transmission of monitoring information,by the use of information embedding position scrambling method and embedding the disturbance data,and designed a kind of combination on LSB and DCT algorithm to improves the watermark extraction difficulty. The paper gives a concrete plan of the system realization,and conducted a field test and analysis. The experiments show the effectiveness of the algorithm and the system could transport Military Railway Transportation monitoring information hiding.
