摘要
提供了一种以符号的冗余编码保留隐藏信息的隐藏数据通信技术,以及与该方法相关的数字水印嵌入、提取技术和载体文件的显示技术。介绍了将符号编码成数字代码的若干方法;隐藏通信的数据加载与分离方法;特定字体文件的设计方法;若干对携带水印信息的载体文件进行显示的方法。提出的文本数字水印技术具有水印容量大、视觉影响小、兼容性强等特点。
A hiding information communication technology based on storing hiding information in redundant code of symbol is proposed in this paper, as well as associated methods of embedding, detecting watermarking information and showing files in which watermarking information is embedded. This paper includes several close relational technology as follow： encoding symbol; loading/separating hiding information on/from cartier file; designing the special font library; showing files in which watermarking information is embedded. The proposed text watermarking technology paper has following advantages： carrying more hiding information, little vision influence and good compatibility.
