Abstract

A method and apparatus for creating a link key and enabling a secure communication link between two or more devices in which a biometric information sample is obtained (102); a PIN code is produced using the biometric information sample (104); and a link key is created using the PIN code (106). In another step, the link key may be used to authenticate future communications between devices.

Claims

1. A method for creating and entering a personal identification number (PIN) code for a secure wireless communication, comprising:

obtaining a biometric information sample;

utilizing a transform function to transform the biometric information sample into a PIN code; and

creating a link key using said PIN code.

2. The method of claim 1 wherein the obtaining a biometric information sample further comprises obtaining at least one of:

a fingerprint sample, a palm print sample, a toe print sample, a retina image sample, a hand geometry sample and a handwriting sample.

3. The method of claim 1 wherein the step of utilizing further comprises producing a numeric PIN code.

4. The method of claim 1 wherein the step of utilizing further comprises producing an alphanumeric PIN code.

5. The method of claim 1 wherein the step of utilizing further comprises producing a PIN code having at least 16 bytes.

6. (canceled)

7. A method for creating and entering a personal identification number (PIN) code for a plurality of devices, comprising:

obtaining a first biometric information sample for a first device;

utilizing a transform function to transform the biometric information sample into a first PIN code;

obtaining a second biometric information sample for a second device;

utilizing the transform function to transform the biometric information sample into a second PIN code identical to said first PIN code using said second biometric information sample; and

creating a link key for said first device and said second device using said first PIN code and said second PIN code.

8. The method of claim 7 wherein said first biometric information sample comprises at least one of:

a fingerprint sample, a palm print sample, a toe print sample, a retina image sample, a hand geometry sample and a handwriting sample.

9. The method of claim 7 wherein said PIN code comprises an alphanumeric PIN code having at least 16 bytes.

10. The method of claim 7 wherein said PIN code comprises a numeric PIN code having at least 16 bytes.

18. An apparatus for creating and entering a personal identification number (PIN) code and creating a link key for multiple devices, comprising:

a biometric imaging apparatus;

a PIN code generators, interfacing with said biometric imaging apparatus, to receive a biometric information sample from the biometric imaging apparatus and to utilize a transform function to transform the biometric information sample into a PIN code; and

a link key creators, interfacing with said PIN code generator, to create a link key through employment of the PIN code.

19. The apparatus of claim 18 further comprising a controller interfacing with said link key creator.

20. The apparatus of claim 19 further comprising a transceiver interfacing with said controller.

21. The apparatus of claim 18 wherein a first one of said multiple devices comprises a mobile telephone and a second one of said multiple devices comprises a wireless headset.
