  Abstract

In this paper, we propose feature based character watermarking methods based on geometrical features specific to characters of text in document image. The proposed methods ca satisfy both data capacity and robustness simultaneously while none of the conventional methods can. According to the characteristics of characters, watermark can be embed or detected through changes of connectivity of the characters, differences of characteristics of edge pixels or changes of area of holes. Experimental results show that our identification techniques are very robust to distortion and have high data capacity.
