Researches on Text Image Watermarking Scheme Based on the Structure of Character Glyph
Yu Xin Liu, Wei Guo, Wen Fa Qi · Applied Mechanics and Materials · 2015
For the poor robustness of current text watermarking schemes, this paper proposed a text watermarking scheme based on the structure of Chinese character glyph. In this method, the different glyphs of character with same semantic is constructed by modifying the connections of Chinese character strokes located on the junction point of skeleton curve, which represents the different digital watermarking information bit strings. Extensive experimental results show that the proposed scheme is effective to resist print-and-scan, copy, photograph attacks etc. It can achieve the purpose of hiding information in paper documents and can be used for information tracking.
