Private Location Sharing for Decentralized Routing services. (arXiv:2202.13305v2 [cs.CR] UPDATED)

Data-driven methodologies offer many exciting upsides, but they also
introduce new challenges, particularly in the realm of user privacy.
Specifically, the way data is collected can pose privacy risks to end users. In
many routing services, a single entity (e.g., the routing service provider)
collects and manages user trajectory data. When it comes to user privacy, these
systems have a central point of failure since users have to trust that this
entity will not sell or use their data to …
