Abstract
Watermarking is widely being explored as an effective means of providing copyright protection for digital multimedia data, and there has been increasing interest in applying watermark to digital raster map for the same purpose. Tile map, however, subjected to a very different feature from other multimedia data. Thus, the watermark scheme designed for image can not be directly applicable to tile map. The purpose of this paper is to propose a novel feature based watermarking algorithm for tile map. First of all, characteristics of tile map have been analyzed and corresponding requirements of watermarking algorithm has been discussed. Then, the watermark embedding and detection algorithm concerning features for tile map have been proposed. Finally, experiments have been conducted to verify the proposed algorithm. The experimental results have shown that the algorithm has excellent invisibility, and it is able to resist various attack behavior such as adding noise, compression, stitching and format conversion.
