| 摘 要： | 针对目前矢量地理空间数据数字水印技术的需求,从矢量地理空间数据特点分析出发,运用矢量地理空间数据线状、面状要素具有的冗余数据的特性,首先在矢量地理数据中增加冗余数据点,然后通过控制冗余点在线状要素上的移动来嵌入水印信息,实现了高保真的矢量地理空间数据数字水印算法,最后对嵌入水印后数据的可用性以及算法的鲁棒性进行了试验分析。

| Abstract: | Considering the needs of current vector geospatial data digital watermarking technologies,basing on the characteristic analysis of vector geospatial data,using the redundant data characteristic in the linear,surface elements of vector geospatial data,the redundant data point was added into vector geographic data.And then the watermark information was embedded into the data by controling the redundant data point to move on the line features.A high-fidelity geospatial data vector digital watermarking algorith... |
