Abstract

A car authentication system using telematics and a smart card includes a part unit, a communication unit, and a database server. The part unit includes parts that are provided with respective unique identification numbers and operate in cooperation with one another through CAN communication. The communication unit is provided in a car, is provided with a smart card to provide user information, and is connected to the part unit. The database server stores user information of registered cars and enables telematics communication with the car so that it can compare the user information from the smart card with the stored user information. Based on the comparison, the respective parts can be activated or deactivated.

Claims

1. A car authentication system using telematics and a smart card, comprising:

a part unit including parts that are provided with respective unique identification numbers and operate in cooperation with one another through Controller Area Network (CAN) communication;

a communication unit provided in a car for telematics communication, provided with a smart card for provision of user information, and connected to the part unit through CAN communication; and

a database server storing user information of registered cars and configured to enable telematics communication with the car so that the database server compares the user information received from the smart card with the user information stored in the database server, provides operating signals to the communication unit to activate the respective parts through CAN communication if the user information received from the smart card matches the user information stored in the database server, and provides OFF signals to deactivate the respective parts by turning off CAN buses of the part unit if the user information received from the smart card does not match the user information stored in the database server.

2. The car authentication system as set forth in claim 1, wherein the telematics communication between the database server and the communication unit is performed using High-Speed Downlink Packet Access (HSDPA) and the smart card installed in the communication unit is a detachable Universal Subscriber Identify Module (USIM) card.

3. The car authentication system as set forth in claim 1, wherein when the user information is changed, the database server updates user information.

4. The car authentication system as set forth in claim 1, wherein:

the part unit transfers the identification numbers of the respective parts to the database server through the communication unit; and

the database server further stores part information of the registered cars and is configured to enable telematics communication with the communication unit so that the database server compares the identification numbers with the part information stored in the database server and, if it is determined that they are matched, transmits operating signals to the communication unit to activate the part or parts while, if they are not matched, turns off CAN bus or buses of the part or parts to deactivate the part or the parts.

5. The car authentication system as set forth in claim 4, wherein the telematics communication between the database server and the communication unit is performed using High-Speed Downlink Packet Access (HSDPA) and the smart card installed in the communication unit is a detachable Universal Subscriber Identify Module (USIM) card.

6. The car authentication system as set forth in claim 4, wherein when the part information is changed, the database server updates part information.

7. A method for authenticating use of a car including parts that operate in cooperation with one another through CAN communication, comprising:

storing user information of registered cars in a database server;

storing user information in a smart card to be installed in a communicated unit of the car;

comparing the user information stored in the smart card with the user information stored in the database server; and

providing operating signals to the communication unit to activate the parts through CAN communication if the user information stored in the smart card matches the user information stored in the database server, and providing OFF signals to deactivate the parts by turning off CAN buses thereof if the user information stored in the smart card does not match the user information stored in the database server.

8. The method as set forth in claim 7, wherein the comparison is performed through telematics communication between the database server and the communication unit and the telematics communication is performed using High-Speed Downlink Packet Access (HSDPA) and the smart card is a detachable Universal Subscriber Identify Module (USIM) card.

9. The method as set forth in claim 7, further comprising updating the user information.

10. The method as set forth in claim 7, further comprising:

providing the parts with respective unique identification numbers;

storing part information of the registered cars in the database server;

comparing the identification number of a part or the identification numbers of the parts with the part information; and

activating the part or parts if the identification number or numbers match the part information, and deactivating the part or parts by turning off CAN bus of buses thereof if the identification number or numbers does not match the part information.

11. The method as set forth in claim 10, wherein the comparison is performed through telematics communication between the database server and the communication unit and the telematics communication is performed using High-Speed Downlink Packet Access (HSDPA) and the smart card is a detachable Universal Subscriber Identify Module (USIM) card.

12. The method as set forth in claim 10, further comprising updating the part information.
