Abstract :
In view of the problems of small capacity to carry hidden information and weak robustness, this paper presents a new Chinese text digital watermarking technology based on cognitive features of human psychology, even by changing the edges number of the junction in Chinese characters, design a variety of characters with different breaking and linking stroks in the same semantic, and encoded these characters which have different structures appropriately, carried the digital watermarking information using of the topological structure of Chinese characters. The technology has many characteristics as followings: small visual impact; higher anti-attack ability.
