With the ubiquity of smartphones, Location Based Services (LBS) have obtained massive interest and grow to be more famous and important currently. However, using LBS it also represents an ability hazard to the privacy of the consumer's vicinity. In this paper, with the reason of consulting spatial rank, a popular LBS that provides statistics approximately points of interest (POI) within a certain distance, we gift a green vicinity base and that preserves privateers query answer, referred to as EPLQ. Specifically, to reap privacy preservation Space rank query, we suggest the first predicate only encryption scheme for the inner product range (IPRE) that can be used to locate if a position is within a given circular location in a manner that preserves privacy. To reduce query latency, we additionally designed a tree index structure to hold privateers in EPLQ. The detailed protection evaluation confirms the safety properties of EPLQ. In addition, sizeable experiments are accomplished, and the outcomes display that EPLQ could be very efficient in retaining privateness spatial range query on subcontracted encrypted records. In precise, for a cellular LBS consumer who uses an Android smartphone, 0.9 s is important to generate a query, and additionally handiest calls for a Commodity notebook, which plays the role of the cloud in our experiments, a few seconds to search for factors of hobby.
