Text zero-watermark based on using strokes of Chinese characters
Jianshou Pan · Computer Engineering and Applications Journal · 2013
Aiming at problems of difficult embedding of Chinese text digital watermarking,weak invisibility and weak robustness,this paper presents a novel Chinese zero-watermarking algorithm based on the number of strokes of Chinese characters.Through combining the frequency of use of Chinese characters in the text,the most frequently used Chinese characters can be got.This paper uses the number of strokes of the most frequently used Chinese characters as a sequence of the text feature,then generates a set of registration key using this sequence and the watermark information.This experiment result shows that the algorithm achieves simply and has good visibility and robustness.
