Abstract
Nowadays due to the advancements in spatial data acquisition technologies, data acquisition technologies are producing mass high precision spatial data. To store such high precision data onto the database is a big challenge today. Spatial database is different from relational database as it contains data along with its location, so security concerns of spatial database are also different from relational data. Thus spatial data requires special security policies and implementation of these security policies. In this work, a secure access control mechanism for geospatial data is developed. In this method, security is provided on two levels. In first level, authorization to every user is provided; thus a user can access only that part of spatial database, over which he has authority to access. In second level, access is controlled over an image; based on the location over which a user needs to access data and access is provided only to that part of an image.
