Biometric authentication proximity card
First Claim
Patent Images
1. A device comprising an authentication system for verifying that the user of the device is the authorized user, the authentication system comprising:
- a reader for sensing and reading a biometric datum of a user;
a memory for storing an authorized biometric datum;
a comparator, responsive to the reader and the memory, for comparing the read biometric datum to the stored biometric datum;
a pseudo-random generator, responsive to the comparator, for generating a pseudorandom personal identification number (PIN) when the read fingerprint and the stored fingerprint are equivalent; and
a wireless transmitter for sending an identifying signal comprising the pseudorandom PIN to a receiving device when the read fingerprint and the stored fingerprint are equivalent.

Abstract
A biometric proximity card and an access system cooperating with such card are disclosed. The card has a biometric sensor, and a memory storing a reference biometric datum, for example, a fingerprint, for an authorized user. Only when a biometric datum of an actual user matches the stored biometric datum, a pseudorandom PIN generator generates a one-time passcode that can be detected and validated by a door panel or other proximity sensor controlling access to a building or other resource.

9. A method for verifying that a user of a device is an authorized user in order to allow or deny access, the method comprising the steps of:
-
sensing and reading a fingerprint of a user of the device;
comparing the read fingerprint with a stored fingerprint of the authorized user of the device;
generating a pseudo-random personal identification number (PIN) when said read fingerprint is equivalent to the stored fingerprint, said PIN being used to verify activation of said device;
and transmitting the pseudo-random PIN to a proximity sensor of an access control system. - View Dependent Claims (10, 11, 12, 13)

14. A device comprising an authentication system for verifying that the user of the device is the authorized user, the authentication system comprising:
-
a reader for sensing and reading a biometric datum of a user;
a memory for storing an authorized biometric datum;
a comparator, responsive to the reader and the memory, for comparing the read biometric datum to the stored biometric datum;
a wireless transponder responsive to a proximity sensor for sending an identifying signal to the proximity sensor when the read fingerprint and the stored fingerprint are equivalent; and
a power supply on the device to enable the device to commence reading and comparing the biometric datum before entering an operative proximity of the proximity sensor. - View Dependent Claims (15, 16, 17, 18)
