Biometrics

• Definition
• Automated measurement of Physiological and/or
  behavioral characteristics to determine or
  authenticate identity

5
Biometrics

• Automated measurement
• No human involvement.
• Comparison takes place in Real-Time.
• DNA is not a Biometric

6
Biometrics

• Physiological and/or behavioral characteristics
• Behavioral
• User speaks.
• Types on a keyboard.
• Signs name.
• Physiological
• Fingerprint
• Hand
• Eyes
• Face

7
Biometrics

• determine or authenticate identity
• Identification Systems
• Who am I?
• Determine Identity
• Verification Systems
• Am I who I claim to be?
• Authenticate Identity

8
Biometrics

• determine or authenticate identity
• Verification Systems (cont)
• More accurate.
• Less expensive.
• Faster.
• More limited in function.
• Requires more effort by user.

9
Biometrics

• Benefits
• Security
• PC, Network, Web
• Physical access to Buildings/Rooms
• Accountability
• Audit Trails
• Recordkeeping
• Convenience
• Savings

10
Biometrics

• Primary drivers
• Size and cost decreased.
• Improved FAR, FRR FTE
• Mature standards
• BioAPI
• BAPI
• Public awareness

Biometrics

• Identification and verification
• Finger scan
• Iris scan
• Retina scan
• Facial scan (optical and infrared)
• Verification only
• Hand Geometry
• Voice Print
• Keystroke Behavior
• Signature
• Other Biometric Technologies in the making.

13
Biometrics

• Finger scan Measures unique characteristics in a
  fingerprint (minutiae)
• Crossover
• Core
• Bifurcations
• Ridge ending
• Island
• Delta
• Pore

14
Biometrics

• Iris scan Measures unique characteristics of the
  iris
• Ridges (rings)
• Furrows
• Straitions (freckles)

15
Biometrics

• Retina scan Measures unique characteristics of
  the retina.
• Blood vessel patterns
• Vein patterns

16
Biometrics

• Facial scan Uses off-the-shelf camera to
  measure the following facial features
• Distance between the eyes.
• Distance between the eyes and nose ridge.
• Angle of a cheek.
• Slope of the nose.
• Facial
• Temperatures.

17
Biometrics

• Hand scan measures the top and side of the
  hand, not the Palm.
• Hand Geometry.
• Most widely used technique for physical access.
• INSpass system

18
Biometrics

• Voice scan Measures the sound waves of human
  speech.
• user talks to a microphone a passphrase.
• Voice print is compared
• to a previous one

19
Biometrics

• Keystroke scan Measures the time between strokes
  and duration of key pressed.
• Most commonly used in systems where keyboard is
  already being used.

20
Biometrics

• Signature scan Measures speed, pressure, stroke
  order an image of signature.
• Non-repudiation

21
Biometrics

• Biometric techniques still in the drawing board
• Vein scan vein pattern in back of the hand.
• Lip movement camera captures images of how user
  lips move while user speaks a passphrase.

• cultural or religious beliefs

27
Biometrics

• Bioprivacy Framework (25 best practices)
• Scope Capabilities
• Data Protection
• User Control of Personal Data
• disclosure, auditing and accountability.

28
Biometrics

• Scope Capabilities
• Limit system scope.
• Limit storage of identifiable biometric data.
• Data Protection
• Security Tools
• Encryption
• private networks
• secure facilities
• Limited System Access

29
Biometrics

• User Control of Personal Data
• Allow user un-enrollment (voluntarily)
• Allow user view, correct and update data
• Disclosure, Auditing and Accountability
• Explain system purpose
• Third party auditing
