Abstract
Disclosed is a vehicle information inquiry method including a logging step of acquiring an event ID for sharing anonymized vehicle information and vehicle travel information corresponding to the event ID from an external device, by a central server, a query step of receiving an inquiry about the event ID and the vehicle travel information corresponding to the event ID from an inquiry server, by the central server, and a responding step of transmitting the vehicle travel information corresponding to the event ID received from the inquiry server to the inquiry server, by the central server.
Claims14
A vehicle information inquiry method comprising:
- acquiring an event ID for sharing anonymized vehicle information and vehicle travel information corresponding to the event ID from an external device, by a central server;
- receiving an inquiry about the event ID and the vehicle travel information corresponding to the event ID from an inquiry server, by the central server;
- and
- transmitting the vehicle travel information corresponding to the event ID (hereinafter, ‘queried event ID’) received from the inquiry server to the inquiry server by transmitting authentication information corresponding to the queried event ID to the inquiry server, by the central server, wherein transmitting the vehicle travel information further comprises:
- a first authentication step of acquiring an authentication information signature obtained by performing a digital signature on the authentication information using a user private key, the authentication information, and the event ID from the inquiry server, by the central server;
- a second authentication step of verifying the acquired authentication information signature based on user authentication information corresponding to the queried event ID, and determining whether the vehicle travel information transmitted to the inquiry server belongs to a vehicle corresponding to the queried event ID, by the central server;
- and
- a third authentication step of transmitting a result of determining whether the vehicle travel information transmitted to the inquiry server belongs to the vehicle corresponding to the queried event ID to the inquiry server, by the central server.
