Recently years, vector map has many advantages than raster map when it is used in many domains as research, education, military or digital map services. And in most cases vector map data contains confidential information which must be kept away from unauthorized users. Moreover, the producing process of a vector map is considerably complex, and the maintenance of a digital map requires substantial monetary, human resources. With the rapid development of vector map contents, a large volume of valuable vector map dataset has been illegal distributed by pirates, hackers or unauthorized users. Therefore the problem focuses on how to protect the vector map data for multimedia applications, storage and transmission. This paper presents the selective encryption algorithm for vector map protection for storage, transmission, distribution to authorized users. In proposed algorithm, we just select some values of polylines and polygons in DCT domain to encrypt by random algorithms and cryptography. Experimental results verified that proposed algorithm is effectively and security. Maps are changed whole after encryption process, and unauthorized users cannot access to copy or use them. Encrypted maps do not alter the size of file and it does not have loss accuracy. The error between original map and decrypted map is approximate zero

“…Consequently, GIS vector map data protection is necessary to prevent illegal duplication and distribution. GIS vector map security includes copyright protection [2][3][4], access control for users, and vector map data encryption in order to prevent attacks or illegal distribution during storage and transmission, and damage in the integration process of geographical information [5][6][7][8][9][10][11][12][13][14]. However, access control on the Web is unable to prevent attacks or illegal duplication and distribution, and watermarking techniques are only useful in identifying ownership and for copyright protection, while unauthorized users should not be able to see, attack, or extract GIS vector map content.…”

In recent years, GIS (Geographical Information System) vector maps are widely used in everyday life, science, and the military. However, the production process of vector maps is expensive, and a large volume of vector map data is easily stolen and illegally distributed. Therefore, original providers desire an encryption solution to encrypt GIS vector map data before being stored and transmitted in order to prevent pirate attacks and to ensure secure transmission. In this paper, we propose an encryption algorithm for GIS vector map data for preventing illegal copying, and ensuring secured storage and transmission. Polyline/polygon data of GIS vector maps are extracted to compute a backbone object. The backbone object is then selectively simplified by the multi-scale simplification algorithm in order to determine the feature vertices of the backbone object. The feature vertices of the backbone object are encrypted by the advanced encryption standard and the secret key. Finally, all vertices of the backbone object are randomized by the random Gaussian distribution algorithm to obtain the encrypted GIS vector map. Experimental results show that the entire map is altered completely after the encryption process. The proposed method is responsive to the various GIS vector map data formats, and also provides better security than previous methods. The computation time of the proposed method is also significantly shorter than that of previous methods.
