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

12
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.

  • BioPrivacy Concerns

24
Biometrics
  • False Acceptance Rate (FAR)
  • False Rejection Rate (FRR)
  • Failure To Enroll Rate (FTE)
  • Ability To Verify (AVT)
  • AVT (1 - FTE)(1 - FRR)

  • Agenda
  • Video
  • Biometric Overview
  • Biometric Technologies
  • Accuracy Metrics
  • BioPrivacy Concerns

26
Biometrics
  • Informational privacy concerns
  • Misuse
  • Addressed by
  • System Design
  • Careful Audit
  • Personal privacy concerns
  • 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
