Text Watermarking Technology Based on Storing Hiding Information in Redundant Code of Symbol
利用字符的冗余编码携带隐藏信息的文本数字水印技术*

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 carrier 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.
