摘　　要：文章针对利用格式化文本进行数据隐藏较为困难的问题,提出了一种基于RTF文档中控制命令字符对大小写不敏感进行编码而达到数据隐藏目的的数据隐藏方法。首先,搜索RTF文档中所有控制命令字符;其次,按照对控制命令字符第一个字母和前两个字母大写分别编码成"0"和"1"的规则进行编码;最后,按此规则将密文信息按位进行编码并写入RTF文档;提取密文的解码过程按规则反向进行。该方法不改变原文档大小,编码简单,实现方便。Aiming at the difficult data hiding using formatted text, this paper proposes a data hiding method based on the case insensitivity of control command characters in the RTF format document to achieve data hiding. First search for all control command characters in the RTF document. Secondly, encode the rules of encoding the first letter and the first two uppercase letters of the control command characters into ＂0＂ and ＂1＂, respectively. And finally, according to the above rules, the information is coded bit by bit and written into the RTF document, the decoding of the extracted ciphertext is done in reverse order. The method does not change the original document size. Coding is simple and convenient.
