For the characteristics of digital watermarking of the vector geospatial data, the DFT (discrete Fourier transform) blind watermarking model is put forward based on QIM(quantized index modulation) idea. First vector geospatial data carries on DFT. The watermark data are embedded in the magnitude of DFT through quantification, then inverse DFT transform, the embedded watermark vector geospatial data is obtained, The experiment results show that the watermark model has good availability, not visibility, as well as format conversion, data translation, rotation has good robustness.
