K-Nearest Neighbor Query Processing
User’s locations and there interested are different. Collecting large amount of data to the user is very difficult. Sometime information is very sensitive; handling the information is very difficult task. Information storage also very big issue. So data owner does not make data accessible in all customers. It’s allowed only paying customers. Users send their current location points and want to know about nearest POIs (Points Of Interests) in NN (Nearest-Neighbor) but data owner does not have that much storage capacity so they are using cloud service. Cloud provides power full storage at low cost but cloud is not fully trusted.
