Abstract
A blind algorithm for watermarking of vector map is presented in this paper. Only the magnitude of the DWT coefficients of vertices extracted from the map is altered to embed the watermark. Watermark can be extracted without original image because the embedding procedure is based on the relationship between the watermark value and the DWT coefficients. Experiment results show that this algorithm is robust to some image processing operations.Keywords
