摘　　要：文本水印技术可以有效地保护数字作品的版权,防止盗版、侵权等行为。针对维吾尔文数字作品版权保护问题,通过分析维吾尔文左向连写、书写落于基线等特征,根据现有文档结构水印算法,提出基于行移结构的维吾尔文文本水印算法。通过行移结构编码嵌入水印信息,依据移动行相对于维吾尔文基线位置的变化,进行水印信息的提取。从水印嵌入和提取的仿真试验结果可知,该算法水印容量小、不可感知性高,具有较强的鲁棒性。Text watermarking technology can effectively protect the copyright of digital works and prevent piracy and infringement etc..Aiming at the copyright protection of Uyghur digital works,this paper proposes a line-shift structure based Uyghur text watermarking algorithm by analyzing the characteristics of left-hand linking and writing falling on the baseline of Uyghur text,according to the existing document structure watermarking algorithm.The watermarking information is embedded by the line-shift structure coding,and the watermarking information is extracted according to the change of the position of the moving line relative to the Uyghur baseline.The simulation results of watermarking embedding and extracting show that the watermarking capacity of the algorithm is small,the imperceptibility is high,and the algorithm has strong robustness.
