Abstract
An in-vehicle device includes a storage unit storing a PIN code and an in-vehicle device ID kept confidential for a user and registered one for each vehicle; a first authentication unit determining whether the in-vehicle device is allowed to be connected to a mobile terminal on the basis of a comparison of the PIN code; a second authentication unit requesting an in-vehicle device ID from the mobile terminal that has been connected through authentication performed by the first authentication unit and authenticating the mobile terminal by comparing the in-vehicle device ID transmitted from the mobile terminal in response to the request with the in-vehicle device ID registered in the in-vehicle device; and a data transmission unit transmitting predetermined vehicle data, obtained from a vehicle equipped with the in-vehicle device and indicating a vehicle state, to the mobile terminal that has been authenticated by the second authentication unit.
