摘　　要：提出了一种抗地理要素合并攻击的矢量地理数据水印算法.在分析了基于地理要素数据合并攻击对水印检测影响的基础上,按照单个地理要素检测—合并—检测的思想,设计并实现了一种抗数据合并攻击的矢量地理数据数字水印算法.实验分析结果表明,该算法能有效抵抗常见的数据合并攻击,且可检测出合并后数据中的多个不同水印信息.A watermarking algorithm against geographic-feature-based data merging attack was presented.And a watermarking algorithm against data merging attack was presented based on analyzing the influence of geographic-feature-based data merging attack according to the detection-merging-detection thinking for single geographic feature. Experiments show that the proposed algorithm has good performance on the robustness against data merging attack. Additionally,the different watermarks in the merged vector geographic data can be detected by using the algorithm.
