摘要：Today’s mobile devices have inbuilt GPS systems such as smartphones which plays an important role inLocation based services. In location based applications and services users require proving their current locations at aparticular time. There are lots of real time applications in market that helps to track the location of the peoples. Aslocation proof plays a critical role in enabling applications, they are location sensitive. The common gain of all theapplications is that they offer geographical location of a person carrying on GPS enabled device. But sometimes userslies their present locations. The Location Based Services personalize the services they provide or grant access toresources according to the present locations of users. They are used in a variety of contexts, such as traffic monitoring,discount tied to the visit of a particular shop. In most of current schemes, the location of users or devices aredetermined by the device through GPS and forwarded to the Location Based Service provider. So, a user can cheat byhaving his or her device transmitting inexact location to gain access to unofficial or unchartered resources, thus raisingthe issues of verifying the position claimed by a particular user. To counter this commination, Location Based Servicesshould ideally require the requesting device to formally prove that it really is at the claimed location. This intent hasbeen formalized through the concept of location proof which is proving that user was at a present location at a specificmoment in time. The proposed system overcomes the identity issue by using biometric server. Each users identificationis stored at biometric server, biometric server lies between prover and server. The verifier usually has close relationshipwith the prover and biometric server to be trusted enough to gain authorization
