摘要
信息隐藏技术是保障网络通信系统安全的重要部分,它着眼于被隐藏信息本身的 不可探测性,利用该技术可在音频文件中嵌入秘密信息以达到隐蔽通信的目的。首先介绍了基于信息 隐藏技术的隐蔽通信的基本模型,分析了计算机网络中信息隐藏的特点;对网络保密通信中的信息隐藏 技术进行了分类比较,并对信息检测技术进行了研究;最后指出了目前该研究领域的具体应用、存在的 问题及今后的发展趋势。
As an important part of network communication security, information hiding technology focuses on the undete'ctability of hidden message. Using this technology, secret information may be embedded into audio files, so as to realize covert communication. At first, the basic model of covert communication based on information hiding is introduced, and the characteristics of information hiding in network environment are analyzed. Then the information hiding technologies in network secret communication are compared with each other, and methods of checking the hidden information are studied. At last, the application, limitation and trend of development in this research area are pointed out.
