ProLoc: Robust Location Proofs in Hindsight

arXiv:2404.04297v1 Announce Type: new
Abstract: Many online services rely on self-reported locations of user devices like smartphones. To mitigate harm from falsified self-reported locations, the literature has proposed location proof services (LPSs), which provide proof of a device's location by corroborating its self-reported location using short-range radio contacts with either trusted infrastructure or nearby devices that also report their locations. This paper presents ProLoc, a new LPS that extends prior work in two ways. First, ProLoc relaxes prior work's proofs …
