From the perspective of Chinese characters classification,this paper made full use of pictographic characters of the two-dimensional and the human visual characteristics of redundancy,and presented a novel natural text watermarking algorithm based on Chinese characters glyph rebuild.In the algorithm,spited the glyph of Chinese characters to two other's,increasing the content of the document coding redundancy,enhancing the watermark capacity,and by adjusting the properties of characters displaying,enhanced the watermarking imperceptibility.Finally,the experiment proves that the algorithm has both advantages of imperceptibility of format watermarking and robustness of the semantic watermarking,and has large capacity characte-ristics.
