摘      要:Location-Based Services(LBSs)are essential in many application contexts like ride-sharing or navigation *** are cases where users could gain an advantage by submitting fake *** problem faced in this paper concerns the possibility that the geographic location declared by a user is not the actual location in which the user is *** solutions are based on centralized or distributed verification in the literature,and other solutions are based on witnesses or *** this paper,we highlight the limitations of such approaches and propose a new scheme that exploits signals coming from satellites to provide trustworthy location proofs,also respecting users *** proposed approach is decentralized because location proofs are stored by users in a suitably-encrypted way,and a blockchain is adopted to guarantee data integrity and *** show that the proposed approach overcomes the state of the art through a detailed analysis.
