Abstract

A method and system are provided for restricting the use of a vehicle such as an automobile to a person or persons whose fingerprints match biometric data stored within a memory in the vehicle'"'"'s control system. A user'"'"'s digitized fingerprints are stored in a non-volatile permanent ROM in the BIOS of a microcontroller on in a ROM accessed by a microprocessor. The microprocessor'"'"'s primary task is that of executing instructions related to the operation of the vehicle, such as regulating the fuel flow rate, and performing other such tasks. Before the microprocessor can execute its instructions related to its primary task it, must complete and exit a conditional loop of instructions that relate to validating a user'"'"'s "real-input" biometric data. Real scanned fingerprints must be compared with fingerprint(s) stored in ROM. If the result of the compare is a true, i.e. is a match, then the conditional loop is satisfied and the microprocessor can execute its instructions relating to operating the vehicle.

Claims

1. A user programmable biometrically secured control system for preventing an unauthorized use of a vehicle comprising:

a user programmable processor for controlling functions normally associated with the operation of a device within a vehicle;

memory for storing biometrically related data and for storing parameters and instructions related to controlling at least some normal operations of the device;

user programmable means for programming biometrically related data stored in the memory and parameters associated with stored biometrically related data, the parameters for limiting execution of functions normally associated with the operation of the vehicle stored in the memory;

biometric data input sensor for providing "real-input" biometrically related data to one of the memory and the user programmable processor; and

,

means for preventing the processor from, and allowing the process to, execute instructions in accordance with the stored parameters associated with the biometric data input related to controlling at least the functions normally associated with the operation of the vehicle in dependence upon the result of a compare operation, after a comparison has been performed between "real" and previously stored biometrically related data.

2. A user programmable biometrically secured control system as defined in claim 1, wherein said means for preventing the processor from executing instructions includes a user programmable control sequence of instructions.

3. A user programmable biometrically secured control system as defined in claim 1, wherein said biometric data input means comprises a fingerprint scanning input device.

4. A user programmable biometrically secured control system as defined in claim 2, wherein said user programmable control sequence of instructions for preventing the processor from executing instructions includes associated instructions for acquiring "real-input" biometric data and for determining if acquired "real-input" biometric data matches stored biometric data within predetermined limits.

5. A user programmable biometrically secured control system as defined in claim 4, wherein the operation of the vehicle is prevented until a suitable match occurs between acquired "real" biometric related data, and stored biometric data.

6. A user programmable biometrically secured control system as defined in claim 1, wherein the biometric data input means are provided to at least input biometric data of an authorized user to be stored in the memory for later comparison with "real" input data.

7. A user programmable biometrically secured control system as defined in claim 1, including an input terminal for programming the control system.

8. A user programmable biometrically secured control system as defined in claim 7, wherein the input terminal includes a key-pad and a display.

9. A user programmable biometrically secured control system as defined in claim 8, wherein the normal operation of the input terminal is dependent upon a positive compare result after a comparison has been performed between "real-input" and stored biometrically related data.

10. A user programmable biometrically secured control system as defined in claim 1, including means for allowing biometric data of a temporary user to be logged into the system for a predetermined period of time.

11. A user programmable biometrically secured control system as defined in claim 1, including means for allowing biometric data of a user to be logged into the system with associated parameters for limiting execution of the functions normally associated with the operation of the vehicle.

12. A method of validating a user of a vehicle and for allowing a user programmable biometrically secured control system of the vehicle to be operable after said validation, comprising the steps of:

receiving a user'"'"'s biometrically related data from an input device;

comparing at least an aspect of the received biometrically related data with stored biometrically related data;

preventing a processor from executing instructions normally related to the operation of the vehicle when the compared data mis-matches within predetermined limits; and

,

allowing the processor to execute instructions normally related to the operation of the vehicle after the compared data matches, within predetermined limits,

wherein at least one of the stored biometrically related data and the instructions are user programmable.

13. A method as defined in claim 12, comprising the steps of:

receiving a user'"'"'s biometrically related data from an input device;

comparing at least an aspect of the received biometrically related data with stored biometrically related data to produce a comparison result; and

,

when the comparison result is indicative of a match, receiving from the input device a second user'"'"'s biometric data for registration, and programming the biometrically secured control system with data relating to the received biometric data from the second user.

14. A method as defined in claim 12, wherein the step of comparing the data is performed by logic circuitry within the processor.

15. A method as defined in claim 12, further comprising the step of providing a temporary authorized user'"'"'s biometrically related data to a memory for storage.

16. A method as defined in claim 12 further comprising the step of providing an authorized user'"'"'s biometrically related data to a memory for storage after the processor has been allowed to execute instructions normally related to the operation of the vehicle.

17. A method as defined in claim 15 further comprising the step of providing a time interval to the processor relating to the allotted time a temporary authorized user may be validated to operate the vehicle.

18. A method as defined in claim 16 further comprising the step of providing a time interval to the processor relating to the allotted time an authorized user may be validated to operate the vehicle.

19. A method as defined in claim 16, further comprising the step of deleting automatically a authorized user'"'"'s biometrically related data from the memory.

20. A method as defined in claim 12, comprising the steps of:

receiving a user'"'"'s biometrically related data from an input device;

comparing at least an aspect of the received biometrically related data with stored biometrically related data to produce a comparison result;

when the comparison result is indicative of a match, allowing the user to program the control system.
