Rfid tag and method of user verification

Abstract

An identification tag ( 100 ) facilitates use of a secure computer system ( 300 ). The tag ( 100 ) is adapted to be worn on a user's wrist and includes an identification and registration circuit ( 102 ) that includes an identification component ( 106 ), an affiliation component ( 110 ), and a light-emitting diode ( 112 ). The computer system includes an RF identification tag registration device ( 302 ) operable to acquire user physical information and communicate the physical information to a computer ( 202 ), wherein the computer verifies that a valid user is wearing the tag ( 100 ). The identification and registration device ( 302 ) ensures that the physical information communicated to the computer pertains to the user wearing the tag by comparing pulse signals acquired from the user's hand and wrist as the device ( 302 ) is acquiring physical information. The computer ( 202 ) uses the identification information and the affiliation information to log the user into and out of the system ( 300 ), and to associate the identification information with a particular user.

1 . A device for registering an identification tag, the device comprising: 
 a first biometric sensor for acquiring first biometric information from a user wearing the tag;    a second biometric sensor for acquiring second biometric information from the user;    a third biometric sensor for acquiring third biometric information from the user;    an identification tag read component for reading identification information from the tag; and    a communications component for communicating the first biometric information and the identification information to an external device if the second biometric information corresponds to the third biometric information.    
   
   
       2 . The device as set forth in  claim 1 , wherein the first biometric sensor is a fingerprint scanner for acquiring fingerprint information.  
   
   
       3 . The device as set forth in  claim 1 , wherein the second biometric sensor includes a first pulse sensor for acquiring pulse information from a first location on the user's arm.  
   
   
       4 . The device as set forth in  claim 3 , wherein the first pulse sensor includes a finger pulse sensor for acquiring pulse information from the user's finger.  
   
   
       5 . The device as set forth in  claim 3 , wherein the third biometric sensor includes a second pulse sensor for acquiring pulse information from a second location on the user's arm.  
   
   
       6 . The device as set forth in  claim 5 , wherein the second pulse sensor includes a wrist pulse sensor for acquiring pulse information from the user's wrist.  
   
   
       7 . The device as set forth in  claim 5 , wherein the third biometric sensor is proximate the read component such that the third biometric sensor and the read component can only be used simultaneously by one person.  
   
   
       8 . The device as set forth in  claim 7 , wherein the third biometric sensor includes at least two receptacles, and wherein a first of the at least two receptacles is located on a first side of the read component and wherein a second of the at least two receptacles is located on a second side of the read component opposite the first side of the read component.  
   
   
       9 . The device as set forth in  claim 7 , wherein the second biometric sensor is proximate the first biometric sensor such that the second biometric sensor and the first biometric sensor can only be used simultaneously by one person.  
   
   
       10 . The device as set forth in  claim 9 , wherein the second biometric sensor is integral with the first biometric sensor.  
   
   
       11 . The device as set forth in  claim 1 , further comprising a confirmation signal sensor for sensing a confirmation signal generated by the identification tag.  
   
   
       12 . The device as set forth in  claim 11 , wherein the communications component communicates the biometric information and the identification information to the external device if the confirmation signal received by the confirmation sensor is valid.  
   
   
       13 . The device as set forth in  claim 1 , wherein the read component communicates with the tag via a wireless RF signal.  
   
   
       14 . The device as set forth in  claim 1 , wherein the read component communicates with the tag via an infrared signal.  
   
   
       15 . A device for registering an identification tag, the device comprising: 
 a fingerprint scanner for acquiring fingerprint information from a tag;    an identification tag read component for reading identification information from the tag;    a first pulse sensor proximate the fingerprint scanner for acquiring pulse information from the user's finger while the finger engages the fingerprint scanner;    a second pulse sensor for acquiring pulse information from the user's wrist; and    a communications component for comparing the pulse information obtained from the wrist pulse sensor with the pulse information obtained from the finger pulse sensor and communicating the identification information and the fingerprint information to an external device if the pulse information obtained from the wrist pulse sensor corresponds to the pulse information obtained from the finger pulse sensor.
