What Are Biometrics?

• Automated methods of verifying or recognizing a
  living person on the basis of some physiological
  characteristics, such as fingerprint or iris
  patterns, or some aspects of behavior, such as
  handwriting or keystroke patterns.

3
Types of Biometrics

• Fingerprint Recognition
• Facial Recognition
• Iris Recognition
• Retinal Scan
• Hand Geometry

4
Fingerprint Recognition

• Matches a specific fingerprint against a database
  of fingerprints to verify an identity.
• Advantages
• Fingerprints are unique
• Technology involved is reasonably priced
• Commonly accepted practice
• Very accurate
• Difficult to reproduce
• Disadvantages
• More intrusive than username/password type
  identification
• Injuries can effect the fingerprint scanning
  process

5
Fingerprint Identification

• Possible Uses
• Gaining access to a computer system
• Gaining access to a secure facility
• Proof of identification in the US court system
• Airport Security
• ATMs

6
Facial Recognition

• Takes a digital image and compares facial
  features against a database to identify an
  individual.
• Advantages
• Faces are captured in public
• Can be done from a distance
• No physical contact necessary
• Criminal Mug shots readily available
• Disadvantages
• Invasion of privacy

7
Facial Recognition

• Possible Uses
• Smart Home
• Identifying African Elephants
• Security at sporting events
• Airport Security
• To prevent voter fraud

8
Iris Recognition

• Takes a high resolution digital image of an
  individuals irises, and uses pattern recognition
  techniques to verify the individuals identity.
• Advantages
• Internal organism, so it is well protected
• Shape is more predictable
• Iris texture is unique even in genetically
  identical individuals
• Texture stays very stable over long periods of
  time
• Disadvantages
• Incompatible with the fingerprint recognition
  systems that have already been invested in
• Difficult to perform if the individual does not
  cooperate

9
Iris Recognition

• Possible Uses
• Passports
• Border control (United Arab Emirates)
• CANPASS Air (pre-approved, low risk)
• ATMs
• Airport personnel identification
