At the moment, data is stored with a third party in cloud environments and query processing is also done by third party to reduce the amount to maintain the system. Mobile devices with geo-positioning capabilities register users to access information that is applicable to their present and current location. Users are interested in querying about points of interest (POI) in their physical concurrence. e.g. restaurants, cafes, gas station, etc. Objects specialized in various areas of interest (e.g., entertainment, and travel) gather large amounts of geotagged data that appeal to register users. Such data may be observant due to their substance. Furthermore, keeping such information latest form and applicable to the users is not an easy task , so the holder of such datasets will make the data available only to paying customers. Users send their current location as the query parameter and wish to receive as result the nearest POIs, i.e., nearest-neighbors (NNs).
