英文摘要	Recently, the information leaking problem of important a per-based documents has become more and more serious, which is caused by scanning, copying and photographing methods. To deal with it, great development has been made in the text watermarking algorithms based on special font library. However, all the current font libraries are created manually with professional softwares with very low efficiency. Based on this consideration, in this paper, we propose an automatic watermarked font library generation method by modifying vector contour curves of Chinese characters. Firstly, the original vector contour curves data of character glyph is obtained and the skeleton curves are extracted after thinner processing. Then all the key points located on the skeleton curves are searched and filtered by the special rules. In the end, the vector contour curves around the selected key points are modified automatically and saved into a new font library. Experimental results show that the visual effect of the automatically generated watermarked font library by the proposed method is more perfect, which meets the needs of current text watermarking algorithms better. Meanwhile, it dramatically improves the production efficiency of watermarked font library generation with higher application value. ? 2014 IEEE.; EI; CPCI-S(ISTP); 0
