摘要:: 随着计算机网络技术的迅速发展,数字文本的取得已经变得非常方便,因为数字文本易于复制和更改的特性,使得版权保护的问题长期阻碍着数字出版行业的发展,然而文本水印技术的出现为解决这一问题提供了可行的方法.针对中文字符的特性,给出了一种利用人眼生理特性和中文字符的书写变化的文本水印方案.通过调整中文字符偏旁部首的位置关系,结合密钥,嵌入水印信息.经过实验分析:该算法具有鲁棒性强、隐蔽性高和抗攻击性强的特点

Abstract:: Along with rapid development of the computer network technology,the digital text obtained has become very convenient,be-cause the digital text is easy to copy and change,the copyright protection problem is hindering the digital publishing industry develop-ment,however the text watermarking technology to solve this problem provides a feasible method. According to the Chinese characters, present a method based on human physiological characteristics and the Chinese character writing changes to the text watermarking scheme. Through the adjustment of Chinese character radical position relations,combined with the key,embedded watermark information. After experimental analysis:the algorithm has strong robustness,high concealment and resistance to aggressive characteristics
