摘要
近年来,随着网络和多媒体技术的快速发展,信息隐藏技术已经成为信息安全领域的一个研究热点。信息隐藏技术是利用宿主信息中的冗余部分,将秘密信息嵌入宿主信息之中,并使其不被其他人发现。首先综述了信息隐藏的基本概念和原理,随后讨论了信息隐藏和密码技术的区别,最后详细介绍了基于文本信息隐藏的几种典型的算法和各自优缺点。
With the rapid development of network and multimedia technologies in recent years. Information hiding has been a research hotspot in the area of information security. Information hiding is a technique which embed some secret message into a certain carrier by means of using the carrier＇s redundancy and avoid these secret messages being revealed by others as far as possible. In this paper,we summarize the general concept and the principle for information hiding. Subsequently, we simply discuss the distinction between information hiding and eneryption. At last,it introduces some typical realization methods of information hiding based on text document in detail, and analyzes the merits and defects of these methods.
