Abstract

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 configured with an authorization ID (identification), comprising:

a first wireless module disposed in the protected object, transmitting an authorization request with the authorization ID, and receiving an authorization response responsive to the authorization request;

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

a central controller disposed in the protected object, coupled to the first wireless module, determining whether the authorization password in the authorization response is valid, allowing the protected object to operate if the authorization password in the authorization response is valid, and disabling the protected object if the authorization password in the authorization response is not valid,

wherein the authorization record is originally set for the remote authorization server to generate the authorization response with the authorization password being valid, when the protected object is not stolen, and the authorization record is further changed by a user so that the remote authorization server generates the authorization response with the authorization password being invalid, when the protected object is stolen.

2. The security system as claimed in claim 1, wherein the central controller renders the protected object operable if the authorization password is valid.

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

4. The security system as claimed in claim 3, wherein the first wireless module transmits the authorization request again before the valid period ends and receives the corresponding authorization response accordingly.

5. The security system as claimed in claim 4, wherein the first wireless module transmits the authorization request periodically before the valid period ends.

6. The security system as claimed in claim 3, further comprising an alarm device, generating a warning signal a predetermined period prior to the end of the valid period.

7. 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.

8. 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.

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

10. A vehicle security system for a vehicle configured with an authorization ID (identification), comprising:

a wireless module disposed in the vehicle, transmitting an authorization request with the authorization ID, and receiving an authorization response responsive to the authorization request;

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

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

a central controller disposed in the vehicle, coupled to the first wireless module, determining whether the authorization password in the authorization response is valid, allowing the vehicle to operate if the authorization password in the authorization response is valid, and disabling the vehicle if the authorization password in the authorization response is not valid,

wherein the authorization record is originally set for the remote authorization server to generate the authorization response with the authorization password being valid, when the vehicle is not stolen, and the authorization record is further changed by a user so that the remote authorization server generates the authorization response with the authorization password being invalid, when the vehicle is stolen.

11. The vehicle security system as claimed in claim 10, wherein the central controller renders the vehicle operable if the authorization password is valid.

12. The vehicle security system as claimed in claim 10, wherein the authorization response comprises a valid period, indicating the validity period of the authorization response.

13. The vehicle security system as claimed in claim 12, wherein the wireless module transmits the authorization request again before the valid period ends and receives the authorization response accordingly.

14. The vehicle security system as claimed in claim 13, wherein the wireless module transmits the authorization request periodically before the valid period ends.

15. The vehicle security system as claimed in claim 12, further comprising an alarm device, generating a warning signal a predetermined period prior to the end of the valid period.

16. A security method for protecting a protected object configured with an authorization ID (identification) and connected with a remote authorization server, comprising:

transmitting, by a wireless module disposed in the protected object, an authorization request with the authorization ID;

generating, by the remote authorization server, an authorization response with an authorization password from an authorization record in accordance with the authorization ID, in response to the authorization request;

determining, by the protected object, whether the authorization password in the authorization response received from the remote authorization server is valid;

allowing the protected object to operate if the authorization password in the authorization response is valid; and

disabling the protected object if the authorization password is not valid,

wherein the authorization record is originally set for the remote authorization server to generate the authorization response with the authorization password being valid, when the protected object is not stolen, and the authorization record is further changed by a user so that the remote authorization server generates the authorization response with the authorization password being invalid, when the protected object is stolen.

17. The security method as claimed in claim 16, the authorization response comprises a valid period, indicating the validity period of the authorization response.

18. The security method as claimed in claim 16, 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.

19. The security method as claimed in claim 18, 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.
