Dramatic advancements in Geographic Information Systems (GIS) and computer technologies resulted in a wide availability of rich-knowledge GIS digital vector maps that are easily accessible and downloadable through the world wide web. This led to the need of copyright protection systems to protect the rights of the producers of these maps. Unlike the research on copyright protection for raster/image data types, the research for vector map data is less documented. This article surveys and classifies the GIS vector map copyright protection research papers published between 2000 and 2014, towards a thorough understanding of the-state-of-the-art, addressing significant limitations of previous review articles, and outlining effective recommendations for future research directions.

Digital image watermarking is one of the proposed solutions for copyright protection of multimedia data. This technique is better than Digital Signatures and other methods because it does not increase IntroductionDigital image watermarking is a process of embedding a piece of digital content (image) into the original image and also it protects digital content from illegal manipulations. The hidden watermark should be inseparable from the host image and robust enough to resist any manipulations while preserving the image quality [1]. Watermarking adds the additional requirement of robustness. An ideal watermarking system would embed an amount of information that could not be removed or altered without making the cover object entirely unusable [2]. So, watermarking is mainly to prevent illegal copy or claims the ownership of digital media. It is a measure of immunity of watermark against attempts to image modification and manipulation like compression, filtering, rotation, collision attacks, resizing, cropping, etc [3]. In order to minimize the damage of the original image and enhance the robustness, a kind of algorithm has been proposed based on the image being layered. At present, the wavelet decomposition method is the most familiar method based on this kind of algorithm [4][5][6].Cao [7] proposed a watermarking algorithm based on transform domain. This algorithm has some robustness characteristics, but it is not efficient to resist the 1/4 and 1/2 heavily cropping. Dai [8] proposed a digital image blind watermarking algorithm based on wavelet transform, which can efficiently resist the cropping attack, but the robustness to resist the noise attack is not strong. Zhang [9] also proposed a digital image watermarking technology based on wavelet transform, which is operated easily, but the ability to resist the noise attack is not strong. To improve the robustness of digital image watermarking method, this paper proposes a new algorithm with stronger robustness to resist the attacks of impulse noise and cropping based on robust principal component analysis (RPCA) and discrete cosine transform (DCT).

“…Although many watermarking schemes have been proposed [1][2][3][4][5][6][7], most of them modify the map more or less to embed the watermark in it. For a vector map, which is sensitive to the precision, any form of distortion is insufferable.…”

With the rapid development of GIS and computer techniques, vector map data has been widely used in many fields. Since the production of map data is very costly, illegal copying will result in huge loss for data owners. In order to protect the copyright of vector data, digital watermarking has been employed in recent years. In this paper, a zero-watermarking scheme for vector map data is proposed. In the proposed scheme, FVDR (feature vertex distance ratio) is constructed based on the feature vertices of objects. The feature data, FVDR, is combined with watermark to generate the zero-watermark. Due to the specially designed cover data, the proposed scheme is robust to geometrical attacks, vertex attacks, and object attacks. The results of extensive experiments also demonstrate the robustness of the proposed scheme.
