Abstract

A security system. The security system for a protected object comprises a first wireless module, a central controller, and a remote authorization server. The first wireless module and the central controller are disposed in the protected object. The first wireless module transmits an authorization request with an authorization ID (identification) of the protected object, and receives an authorization response. The central controller is coupled to the first wireless module, and allows the protected object to operate in accordance with the authorization response. The remote authorization server, responsive to the authorization request, generates the authorization response from an authorization record thereof in accordance with the authorization ID, and transmits the authorization response.

Claims

1. A security system for a protected object, comprising:

a first wireless module disposed in the protected object, transmitting an authorization request with an authorization ID (identification) of the protected object, and receiving an authorization response;

a central controller disposed in the protected object, coupled to the first wireless module, allowing the protected object to operate in accordance with the authorization response; and

a remote authorization server responsive to the authorization request, generating the authorization response from an authorization record thereof in accordance with the authorization ID, and transmitting the authorization response.

2. The security system as claimed in claim 1, wherein the authorization response comprises an authorization password.

3. The security system as claimed in claim 2, wherein the central controller allows the protected object to operate properly if the authorization password is valid.

4. The security system as claimed in claim 3, wherein the central controller renders the protected object operable if the authorization password is valid.

5. The security system as claimed in claim 1, wherein the authorization response comprises a valid period, indicating the validity period of the authorization response.

6. The security system as claimed in claim 5, wherein the first wireless module transmits the authorization request again before the valid period ends and receives the corresponding authorization response accordingly.

7. The security system as claimed in claim 6, wherein the first wireless module transmits the authorization request periodically before the valid period ends.

8. The security system as claimed in claim 5, further comprising an alarm device, generating a warning signal a predetermined period prior to the end of the valid period.

9. The security system as claimed in claim 1, wherein the authorization record can be changed by a user.

10. The security system as claimed in claim 1, wherein the remote authorization server comprises a second wireless module receiving the authorization request and transmitting the authorization response.

11. The security system as claimed in claim 1, further comprising a transceiver connected to the remote authorization server via a network, wherein the first wireless module transmits the authorization request to the remote authorization server through the transceiver and receives the authorization response therethrough.

12. The security system as claimed in claim 1, wherein the protected object is a vehicle.

13. A vehicle security system for a vehicle, comprising:

a wireless module disposed in the vehicle, transmitting an authorization request with an authorization ID (identification) of the vehicle, and receiving an authorization response;

a central controller disposed in the vehicle, coupled to the first wireless module, allowing the protected object to operate in accordance with the authorization response;

a transceiver, receiving the authorization request from the first wireless module and transmitting the authorization response thereto; and

a remote authorization server connected to the transceiver via a network, responsive to the authorization request from the transceiver, generating the authorization response from an authorization record thereof in accordance with the authorization ID, and transmitting the authorization response to the transceiver.

14. The vehicle security system as claimed in claim 13, wherein the authorization response comprises an authorization password.

15. The security system as claimed in claim 14, wherein the central controller allows the vehicle to operate properly if the authorization password is valid.

16. The vehicle security system as claimed in claim 15, wherein the central controller renders the vehicle operable if the authorization password is valid.

17. The vehicle security system as claimed in claim 15, wherein the central controller stops the vehicle if the authorization password is invalid.

18. The vehicle security system as claimed in claim 13, wherein the authorization response comprises a valid period, indicating the validity period of the authorization response.

19. The vehicle security system as claimed in claim 18, wherein the wireless module transmits the authorization request again before the valid period ends and receives the authorization response accordingly.

20. The vehicle security system as claimed in claim 19, wherein the wireless module transmits the authorization request periodically before the valid period ends.

21. The vehicle security system as claimed in claim 18, further comprising an alarm device, generating a warning signal a predetermined period prior to the end of the valid period.

22. The vehicle security system as claimed in claim 13, wherein the authorization record can be changed by a user.

23. A security method for a protected object, comprising:

transmitting an authorization request with an authorization ID (identification) of the protected object;

generating an authorization response from an authorization record in accordance with the authorization ID; and

allowing the protected object to operate in accordance with the authorization response.

24. The security method as claimed in claim 23, wherein the authorization response comprises an authorization password.

25. The security method as claimed in claim 24, wherein the step of allowing the protected object to operate comprises allowing the protected object to operate properly if the authorization password is valid.

26. The security method as claimed in claim 25, wherein the protected object is actuated if the authorization password is valid.

27. The security method as claimed in claim 23, the authorization response comprises a valid period, indicating the validity period of the authorization response.

28. The security method as claimed in claim 23, further comprising transmitting the authorization request with the authorization ID of the protected object again before the valid period ends and generating the corresponding authorization response accordingly.

29. The security method as claimed in claim 28, wherein the step of transmitting the authorization request with the authorization ID of the protected object again comprises transmitting the authorization request with the authorization ID of the protected object periodically.
