Binary document authentication technology based on Chinese character structure hiding
Wang Cui-fang · Computer Engineering and Applications Journal · 2010
This paper proposes a novel data hiding method for binary images authentication based on analyzing the measurement of document images and considering the structure of Chinese character.First unify the pixels flippability scores and the Chinese character structural feature,choose 16 standard modules,and then choose 8 best flip patterns module according to DRDM rule,flip the 8 best flip patterns module to embed watermark.The experiment shows this algorithm has best visual quality,and can be used to location the tampers at the same time.
