Consensus-Based Cooperative Location Proof for Untrusted Devices

Abstract

Abstract Modern Location-based Services depend on the user’s honesty to provide the benefits. Since the location is determined mainly using the user devices, adversarial actors abuse these services for their intent. To address this problem we propose a location-proof method that’ll help Location-based Services to serve genuine users of the service positioned in a particular position at a given time. The proposed solution verifies user location by nearby communication method giving proofs of location tied to a boundary provided by the transmission channel. With the range of 30 meters to 50 meters per location-proof, We also address the issues created by having this kind of location method like privacy and security. Verified by Automated Validation of Internet Security Protocols and Applications (AVISPA), we prove that attacks on the protocol can be easily mitigated. We show that the proposed solution is cost-effective since it does not need additional infrastructure and modification to the hardware.
