Enabling Integrity and Non-transferability of the Location proofs and protects users Privacy

Abstract

Services of Location based are quickly becoming hugely popular. The services based on users' current location, many potential services rely on users' location history, or their spatial-temporal Location. Malicious users are may lie about their spatial-temporal location without a carefully designed security system for users to prove their past locations. In this paper, we present the Spatial-Temporal provenance Assurance with Mutual Proofs (STAMP) scheme. STAMP is designed for MANET mobile users generating location proofs for each other in a distributed setting. It can provide easily to trusted mobile users and wireless access points. STAMP ensures the integrity and non-transferability of the location proofs and protects users' privacy. A semi-trusted Certification Authority is used to distribute cryptographic keys and guard users against collusion by a light-weight entropy-based trust evaluation approach. This prototype implementation on the Android platform shows that STAMP is low-cost in terms of computational and storage resources.
