A Complementary Digital Watermarking Algorithm for Vector Map Data

The characteristic of different watermarking attacks is studied. A watermarking scheme is proposed based on the complementarities of transform-domain and space-domain algorithm. This scheme avoids the disadvantages of the existing algorithms. The experiments of watermarking embedding,attacks and detection are carried out,which demonstrate that our scheme is effective and robust to most of the watermarking attacks.
