Abstract
A current position detection part 15 detects vehicle history information varying with use of a vehicle. A storage part 13 stores the vehicle history information. At authentication, an output part 12 gives a question about the vehicle history information, and the user inputs through an input part 11 an answer to the question. An information processing part 14 determines whether the answer is correct, based on the vehicle history information stored in the storage part 13 and the answer from the user, thereby authenticating the user of the vehicle.
