PROBLEM TO BE SOLVED: To protect each vehicle from a fraudulent operation such as a theft via distributed processing by implementing the authentication number collating process with a collating means on the vehicle side, allowing an operation when the legitimate authentication number is inputted only, and controlling the operation of the vehicle without depending on the operational state of a host computer. SOLUTION: This system 40 is constituted of a vehicle side security device 10, a user terminal device 20, and a center terminal device 30 as the center. The vehicle side security device 10 is accessibly connected to other devices 20, 30 by radio circuits. The authentication number collation process is implemented by a collating means for the authentication number inputted via an authentication number control means, and the operation of a vehicle is allowed only when the legitimate authentication number is inputted via a security control means. The distributed process type authentication number collation function operably controlling the vehicle can be realized without depending on the operational state of the host computer 30. The vehicle can be protected from a fraudulent operation such as a theft via distributed processing for each vehicle. |
