Abstract: 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.

Key words: vector geographic data, digital watermarking, data merging attack, robustness
