Validating Citizen Journalism Reports Through Robust Location Proofs in Hindsight
ProLoc is a location proof service that can retroactively generate region proofs for a device's location at a given time, by correlating the device's self-reported locations and short-range radio encounters with nearby devices. ProLoc includes a novel defense against large-scale collusion attacks involving many fictitious devices.
