The purpose of this approach is to authenticate user's mobile device and to preserve privacy towards location proof. A person's location proof depends on the user's mobile device position. Biometric authentication technique was proposed in order to avoid malicious users from prevaricating their identity. The location proofs are generated by co-located Bluetooth enabled mobile devices. The working of the authors' proposed system is similar to A Privacy-Preserving LocAtion proof Updating System (APPLAUS). To prevent the weak identity of mobile device, the technique of biometric authentication was deployed.
