biometrics
4
Types of biometrics • DNA
• Ear
• Iris matching
• Face recognition
• Fingerprint
• Gait
• Hand Geometry
• Odor
• Signature
• Typing patterns
• Voice recognition
5
Biometrics used for • Authentication
– One to one matching • Identification
– One to many matching
• Security • Alternative to passwords
6
Privacy concerns of biometrics • If your biometrics are stolen or
compromised, can not be reset or replaced • Can be detected without your cooperation
– Surveillance • Creation of databases with information • Implicated in crimes
7
Other ethical concerns with biometrics • Only as good as the initial identification • Accuracy may differ in minority populations • Trade-off between false-positive and false-
negative
8
Case Study • Biometrics in national identity cards
– Which biometric? – When is it issued (e.g. at birth) – Why? – Why not?
