To receive a telematics service, it must first be authenticated, and each automobile (or car navigation system) has typically to be linked to a particular vehicle owner who could authenticate such services. However, an increasing number of drivers use cars that are rented, leased, or obtained through a car-sharing program; in such cases, the present form of car authentication is insufficient. A better system would authenticate the individual who is using a car at a particular time, but is not necessarily the owner. In this paper, we propose a personal authentication infrastructure for next-generation telematics.
