- PlayMob: Privacy Layer for Mobility applications
PlayMob addresses the problem of integrating privacy constraints in mobility applications. The main considered application is dynamic carpooling: how to synchronize a driver and a rider without revealing both their origins and their destinations ?
In fact, the currently existing carpooling services raises serious privacy issues as they reveal a large quantity of location data about their users to other users. We aim at developing a privacy-preserving carpooling service by addressing the following question: how can a couple of mistrustful driver and rider synchronize to find optimal pick-up and drop-off locations without disclosing the exact origin and destination of their journeys. To answer this question, we leverage on existing privacy enhancing technologies to build carpooling services following the privacy-by-
design principle.
PlayMob is an extension of MuPaRo (see below) and also consider others applications such as shortest path or k-shortest paths in multi-modal transportation networks.

- MuPaRo: Multiple Participant Routing
MuPaRo addresses an essential problem for providing dynamic carpooling: how to compute the shortest driver’s and passenger’s paths. Indeed, those two paths are synchronized in the sense that they have a common subpath between two points: the location where the passenger is picked up and the one where he is dropped off the car. The passenger path may include time-dependent public transportation parts before or after the common subpath.
