User-Deﬁned Privacy Grid System for Continuous Location-Based Services
|Name||User-Deﬁned Privacy Grid System for Continuous Location-Based Services|
user always use LBS that is location base service to obtain services depend upon his location. This type service is not secure because of the entrusted server. so new scenario of the grid system comes known as the Dynamic grid service(DGS). it contain 1) only matching operation 2)Secure snapshot and continuous location privacy is guaranteed under our defined adversary models 3)price depend on the on the number of relevant points of interest in the vicinity of the user 4)Although we only focus on range and k-nearest-neighbor queries in this work, our system can be easily extended to support other spatial queries without changing the algorithms run by the semi-trusted third party and the database server, provided the required search area of a spatial query can be abstracted into spatial regions.
