how they are used

• Reason about privacy concerns related to

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?
