Biometrics
             • Biometrics is the study of automated 
                methods for uniquely recognizing humans 
                based upon one or more intrinsic physical 
                or behavioral traits
             • biometric authentication refers to 
                technologies for measuring and analyzing 
                human physical and behavioral 
                characteristics for authentication purposes.

             Biometrics
             • Issues and Concerns
             •   Technology has the potential to do great things. 
             •   It also brings with it the potential to do harm. 
             •  Are concerns surrounding biometric use real or 
                imagined?  
             •  Do our concerns prevent us from seeing the vast 
                potential of the new technologies developed 
                using biometrics

              Biometrics
              Issues and Concerns: This could happen -
              •  DNA is planted at the scene of the crime
              •  Assume another's identity by using the person’s biometrics 
                 or simulating their biometrics. In this way, impersonate 
                 them without arousing suspicion
              •  Fool a fingerprint detector by using a piece of sticky tape 
                 with an authentic fingerprint on it
              •  Fool an iris recognition camera by showing a photo of 
                 another’s iris
              •  Hack into the interface between a biometric device and the 
                 host system, so that a "fail" message gets converted to a 
                 "pass".

       Biometrics
       Issues and Concerns
       •
            Biometric measurements are more 
       difficult to forge  
       •
            Since biometrics more problematic 
       when lost or stolen
