| 摘 要： | 传统的加密通信不具备伪装性,容易被攻击者截取.为了有效地将信息隐藏实现保密通信,设计了一种基于视频数字水印技术的保密通信系统.该系统将文本信息经海明编码后嵌入到离散余弦变换的系数中来实现信息隐藏,采用直流系数的相对变化关系来实现同步和实时随机检测,能有效克服传统加密通信的缺点.实验表明该系统对视频质量影响较小,能实现隐藏信息的可靠传输.

| Abstract: | Traditional secure communication, with no camouflage, is easily intercepted by aggressors. For the purpose of hiding the information and realizing secure communication, one kind of secure communication system based on video digital watermark is designed. This system inserts text information after hanming coding into the DCT(Discrete cosine transform)transformation coefficient to realize information hidding, uses relative relations of direct-current coefficient to realize synchronization and real-time stocha... |
