Abstract

Portable devices, methods, and systems for controlling access to computers and other secure systems such as systems protecting secure premises, by processing data supplied by the individual seeking access to the system and data supplied by the system to which the prospective user seeks access, to determine whether access by the individual is to be authorized or enabled. In one embodiment the invention provides a device for providing a code that may be used to access a system such as a computer or security system. The device comprises an output device and at least one processor. The processor processes data representing a biometric characteristic of a prospective user of the system and a signal provided by the system, and, depending upon a result of the processing, provides to the output device a code that may be used to access the system.

Claims

1. An access control device for providing a code that can be used to access a system, the device comprising:

an output device;

at least one processor that processes, using application programming, information representing a biometric characteristic of a person seeking access to the system and information provided by the system, and, depending on a result of the processing, provides to the output device a code that can be used to access the system;

rewritable, non-volatile memory that stores at least a portion of the application programming;

a sensor that senses the biometric characteristic of the person and provides the information representing the biometric characteristic of the person used by the at least one processor;

a first wireless input device by which the information provided by the system can be wirelessly input to the access control device; and

a second wireless input device by which, data or updates, or both relating to the application programming can be wirelessly input to the access control device and provided to the rewritable memory for storage therein.

2. The access control device of claim 1, wherein the at least one processor conditions providing the code to the output device upon a correlation between the information representing the biometric characteristic and stored biometric information.

3. The access control device of claim 2, wherein the at least one processor determines correlation or not between the information representing the biometric characteristic and the stored biometric information.

4. The access control device of claim 2, wherein the rewritable memory stores the stored biometric information.

5. The access control device of claim 1, wherein the output device is a display device.

6. The access control device of claim 1, comprising a common housing supporting the first and second wireless input devices, the biometric sensor, and the processor.

7. The access control device of claim 6, wherein the housing comprises at least one surface with which is associated a means for identifying the person.

8. The access control device of claim 7, wherein the means comprises at least one of a human readable device and a photograph.

9. The access control device of claim 7, wherein the means comprises machine-readable coding.

10. The access control device of claim 7, wherein the means comprises an electronic device.

13. The access control device of claim 1, comprising an input/output interface which includes the second input device by which the data or updates, or both relating to the application programming can be input to the access control device and provided to the rewritable memory for storage therein and data can be transmitted from the access control device.

14. The access control device of claim 13, wherein the input/output device interface comprises a transceiver.

15. The access control device of claim 14, wherein the transceiver comprises an optical transceiver.

16. The access control device of claim 15, wherein the optical transceiver comprises an infrared transceiver.

17. The access control device of claim 1, wherein the first input device comprises an optical input device.

18. The access control device of claim 1, wherein the first input device comprises a photosensor.

11. A method of providing a code for use in accessing a system, the method performed by an access control device and comprising:

the access control device, using application programming, processing biometric information received from a biometric sensor associated with the access device to establish a correlation between the received biometric information and stored biometric information;

if the correlation satisfies a correlation criteria, the access control device providing to an output device thereof an access code that can be used to access the system, the access code determined by the access control device using information provided by the system and application programming,

otherwise the access control device not providing to the output device a code that can be used to access the system;

the access control device storing in rewritable, non-volatile memory associated with the access device at least some of the application programming;

the access control device receiving at a first input device thereof a first wireless signal which includes the information provided by the system;

the access control device receiving at a second input device a second wireless signal which includes data, or updates, or both relating to the application programming; and

the access control device storing the data and updates in the rewritable memory.

12. The method of claim 11, wherein the access code is session-specific.

19. The method of claim 11 wherein the step of receiving the data and updates comprises receiving the second wireless signal at a wireless input/output interface which includes the second input device, and comprising the step of the access control device transmitting data therefrom via the wireless input/output interface.
