Zhichao Yu, Xiaojun Liu · 2009
In this paper, several technologies of text digital watermarking are studied, and they are categorized according to different embedding modes. On this basis, a text digital watermarking algorithm is designed and implemented. Text digital watermarking generates through some of the synonyms of the word in some position, and different copies has a different watermark. It also provided a preliminary laboratory test results, the results show that: the watermark has a strong robustness to the distortion caused by printing, phototypesetting, scan, fax and re-typing.
