Abstract

Digital elevation model (DEM) data describe the information of ground elevation. So it is important to protect the copyright of digital elevation model data. A lossless visible 3-D watermarking algorithm to protect DEM data is proposed in this paper. The copyright watermarking is embedded in the DEM data by an visible way. The original data, blocked by 3-D visible watermarking, are hidden in the watermarked DEM data by a generalized histogram algorithm. Because the visible watermark blocks a part of DEM data, illegal users are restricted to retrieve. At the same time, 3-D visible watermark can identify the copyright. Without original 3-D watermark data, authorized users can eliminate the 3-D visible watermark and restore the original DEM data lossless by applying the proposed algorithm. It is a blind watermarking algorithm. Experiments demonstrate that the proposed algorithm has satisfactory security and can effectively protect the copyright of DEM data.
