摘要
针对传统加密通信伪装性差,容易被监听截取的问题,文章实现了基于脆弱视频水印技术的隐密通信系统。在该系统中,利用视频图像块之间的能量关系相对稳定这一特征,设计了一种快速可变同步标识的视频数字水印方法。实验表明:采用该方法,系统能在人体视觉难以感知的情况下,很好地实现了隐密信息的伪装、安全传输。
The traceable and vulnerable disadvantage of traditional encryption communication system is still unresolved, and a novel secret communication system based on fragile video watermarking is presented. It was utilized that the relatively stable characteristic of energy relation between the DCT block of image, and a fast variable synchronization marker of video watermarking method was designed in this system. Experimental results show that: In a situation that the human vision is difficult to perceive, the system achieved a good camouflage of the secret information, secure transmission.
