Location-based services (LBS), outsourced encrypted data, privacyenhancing technology, spatial range query. In our safe tourist application or travelling we aims to outsource the lbs data from the lbs provider to the cloud and from the cloud to the lbs provider which protects the privacy related issues of the lbs data. Initially lbs user query for a place to the lbs provider, lbs provider in turn upload the details to the cloud but in the form of encrypted text to prevent the cloud from

When the query of the lbs user matches the details in the cloud the lbs user will retrieve the details and make use of it. In this application it is shown with the demo of a tourist requesting for tourist places tourist is the lbs user and admin is the lbs provider .With the pervasiveness of smart phones, location based services (LBS) have received considerable attention and become more popular and vital recently. However, the use of LBS also poses a potential threat to user's location privacy. In this paper, aiming at spatial range query, popular LBS providing information About POIs (Points of Interest), we present an efficient and privacy-preserving location based query solution, called SPATIAL RANGE. To reduce query latency, we further design a privacy-preserving tree index structure in SPATIAL RANGE. Detailed security analysis confirms the security properties of SPATIAL RANGE. In addition, extensive experiments are conducted, and the results demonstrate that spatial range is very efficient in privacy preserving spatial range query over outsourced encrypted data. In particular, for a mobile LBS user using an Android phone, around 0.9 second is needed to generate a query; and it also only requires a commodity workstation, which plays the role of the cloud in our experiments, a few seconds to search POIs.

Introduction:- A FEW decades ago, location-based services (LBS) wereused in military only. Today, thanks to advances in information and communication technologies, more kinds of LBShave appeared, and they are very useful for not only organiza-tions but also individuals. Let us take the spatial range query,one kind of LBS that we will focus in this paper, as an exam-ple. Spatial range query is a widely used LBS, which allows auser to find points of interest (POIs) within a given distance tohis/her location, i.e., the query point. As illustrated in Fig. 1 ,with this kind of LBS, a user
