“…Scaling refers to altering the size of the map, in both axes by a specific value [16]. Other relevant types of attacks are interpolation [26] and simplification [14] attacks. Simplification attacks refer to the process of removing vertices from the map [14], while interpolation attacks refer to the process of adding new vertices in the map [26].…”

“…5. Interpolation Attack: The interpolation attack refers to the process of adding new vertices to map's borders [26]. Similary to the simplification attack, when the centers of polygons are calculated by averaging the vertices, adding more vertices will change that average.…”

The availability of Geographic Information System (GIS) data has increased in recent years, as well as the need to prevent its unauthorized use. One way of protecting this type of data is by embedding within it a digital watermark. In this paper, we build on our previous work on watermarking vector map data, to improve the robustness to (unwanted) modifications to the maps that may prevent the identification of the rightful owner of the data. More specifically, we address the simplification (removing some vertices from GIS vector data) and interpolation (adding new vertices to GIS data) modifications by exploiting a particular property of vector data called a bounding box. In addition, we experiment with bigger maps to establish the feasibility of the approach for larger maps.

“…Fragile watermarking allows the detection of any tampering with the vector map data [158,159]; however, any small change in the watermark would make it undetectable. This approach has a wide range of applications such as authentication and HV shift 1 [106] integrity protection of the vector maps [204,205].…”

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.

“…This makes watermark embedding more difficult as compared to video, audio images etc. For copyright protection, there have been different works done using the method of digital watermarking [3][4][5][6][7] and also the content authenticity [8][9][10][11][12][13][14] of 2-Dimensional vectors contrasted with various other options available, for example, digital signature and encryption method. The watermarking can give extra security for the important data [15] and save you time for the process of retransmission [11].…”

Because of the need to publish digital maps of several programs, for example, traffic information in a secure format to ensure the preservation of copyrights. The 2-D vector map application encounters security problems of copyright protection that constrain the utilization of vector data map in numerous situations. According to recent researches, it has been concluded that for 2-dimensional vector maps, the technically demanding tasks of existing reversible watermarking plans are getting rotation, scaling and translation (RST) invariance property Attacks, embedding distortion control and high capacity. Specifically, to achieve security performance of the copyright information, we propose the first reversible watermarking scheme by is used linear cellular automata for 2D vector maps that are considered as watermarking to building up new coordinates framework and relative coordinates are built as cover information to ensure High Capacity watermarking as well as gives great invisibility. According to analysis and experiments outcomes, our proposed technique gives very efficiently in, invisibility, and reversibility.
