| 摘 要： | 该文针对在中文文本中嵌入水印比较困难,鲁棒性不高等特点,提出了一种基于汉字笔画的文本水印算法.首先以文本中特定笔画数的汉字为标志,提取其左右相邻汉字的笔画数并转换为一系列代码,然后按照对应比较规则,完成水印嵌入.仿真实验证明该算法嵌入水印容量大,具有较强的隐藏性和鲁棒性,能有效地抵抗格式攻击,以及识别文本字符的删除、添...

| Abstract: | By marking Chinese characters which have the specified number of strokes,this paper introduces a text watermarking algorithm based on the stroke of Chinese characters.Experimental results show that the algorithm has a greater watermarking capacity,stronger robustness and best imperceptibility.At the same time,the algorithm has good robustness against the format attack,and can identify the attacks of deleting and adding characters. |
