Claim 8:
9. A user authentication method for performing a connected vehicle service, the user authentication method comprising:
receiving, at a service terminal, first vehicle identification information from a vehicle system when the vehicle system is turned on;
encrypting, at the service terminal, the first vehicle identification information and terminal identification information of the service terminal, the terminal identification information having been previously stored in the service terminal;

receiving, at a user terminal, the service ID by scanning the optically readable code;
transmitting, at the user terminal, the received service ID to a service server through an external network to request a user authentication;
receiving, at the service server, the service ID from the user terminal;
decrypting, at the service server, the service ID received from the user terminal;
performing, at the service server, the user authentication by comparing information included in the service ID with previously stored second vehicle identification information and the terminal identification information; and
