　　信息隐写是信息安全的重要研究方向之一，其主要研究如何将秘密信息嵌入到特定载体之中，以达到安全通信或版权保护等目的。分析了文本信息隐写的研究现状和存在的不足，设计了一种基于简化字、繁体字替换的中文信息隐写算法。算法对隐写信息进行分段，通过“解释”的方式嵌入分段信息，分段长度可以根据不同的应用需要灵活调整，算法最高嵌入率约为2%。另外，算法可以抵抗对载体文本的重新排版等传统攻击方法。

Information Hiding(IH)is an important research direction of information security. IH mainly researches how to embed secret information into carriers, in order to achieve the objectives of secure communication, watermarking, and so on. This paper analyzes the current status of IH based on text and its shortcomings. A novel information hiding algorithm based on substi-tution of different forms of Chinese characters is proposed. It splits the secret information, and then embeds the sector information into the carrier text by explanation. The sector length can be adjusted according to application requirements. The highest embedding rate of the algorithm is about 2%. In addition, this algorithm can resist traditional attacking method such as re-layout.
