Abstract
Geographical data is under an unsecure environment after released by data owner. The data may be modified in an illegal ways. In this paper, we propose a public watermarking scheme which can verify the integrity of geographical data. The public watermarking scheme contains two algorithms: watermark embedding algorithm and watermark detection algorithm. In the watermark embedding algorithm, a verification vector set is generated based on the dataset, and released to the public. Any end-user can verify the integrity of the dataset by watermark detection algorithm. Experiment results demonstrate that the watermarking scheme has good performance to detection several modifications efficiently, and evaluate the integrity rate at different modification amplitudes.
