Biometrics Definition: “Automated measurement of Physiological and/or behavioral characteristics to determine or authenticate identity” by Alvaro E. Escobar 4
Biometrics “Automated measurement” n. No human involvement. n. Comparison takes place in Real-Time. –DNA is not a Biometric by Alvaro E. Escobar 5
Biometrics “Physiological and/or behavioral characteristics“ 1. Behavioral: – – – 2. – – User speaks. Types on a keyboard. Signs name. Physiological: Fingerprint Hand Eyes Face by Alvaro E. Escobar 6
Biometrics “determine or authenticate identity” n Identification Systems: – – Who am I? Determine Identity n Verification Systems: – – Am I who I claim to be? Authenticate Identity by Alvaro E. Escobar 7
Biometrics “determine or authenticate identity” n Verification Systems (cont): – – – More accurate. Less expensive. Faster. More limited in function. Requires more effort by user. by Alvaro E. Escobar 8
Biometrics n Benefits: – Security n n – – PC, Network, Web Physical access to Buildings/Rooms Accountability Audit Trails Recordkeeping Convenience Savings by Alvaro E. Escobar 9
Biometrics n – – – n n – Primary drivers: Size and cost decreased. Improved FAR, FRR & FTE Mature standards Bio. API BAPI Public awareness by Alvaro E. Escobar 10

Biometrics n – – – – n 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. by Alvaro E. Escobar 12
Biometrics n – – – – Finger scan: Measures unique characteristics in a fingerprint (minutiae) Crossover Core Bifurcations Ridge ending Island Delta Pore by Alvaro E. Escobar 13
Biometrics n – – – Iris scan: Measures unique characteristics of the iris Ridges (rings) Furrows Straitions (freckles) by Alvaro E. Escobar 14
Biometrics n – – Retina scan: Measures unique characteristics of the retina. Blood vessel patterns Vein patterns by Alvaro E. Escobar 15
Biometrics n – – – Facial scan: Uses off-the-shelf camera to measure the following facial features: Distance between the eyes and nose ridge. Angle of a cheek. Slope of the nose. Facial Temperatures. by Alvaro E. Escobar 16
Biometrics n Hand scan: measures the top and side of the hand, not the Palm. – – Hand Geometry. Most widely used technique for physical access. INSpass system – by Alvaro E. Escobar 17
Biometrics n Voice scan: Measures the sound waves of human speech. – – user talks to a microphone a passphrase. Voice print is compared to a previous one by Alvaro E. Escobar 18
Biometrics n Keystroke scan: Measures the time between strokes and duration of key pressed. – Most commonly used in systems where keyboard is already being used. by Alvaro E. Escobar 19
Biometrics n – Signature scan: Measures speed, pressure, stroke order an image of signature. Non-repudiation by Alvaro E. Escobar 20
Biometrics n – – 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. by Alvaro E. Escobar 21

Biometrics n n – False Acceptance Rate (FAR) False Rejection Rate (FRR) Failure To Enroll Rate (FTE) Ability To Verify (AVT) AVT = (1 - FTE)(1 - FRR) by Alvaro E. Escobar 24

Biometrics n – – n n n – Informational privacy concerns: Misuse Addressed by: System Design Careful Audit Personal privacy concerns cultural or religious beliefs by Alvaro E. Escobar 26
Biometrics n – – Bioprivacy Framework (25 best practices) Scope & Capabilities Data Protection User Control of Personal Data disclosure, auditing and accountability. by Alvaro E. Escobar 27
Biometrics n – – Scope & Capabilities: Limit system scope. Limit storage of identifiable biometric data. n Data Protection: – Security Tools: n n n – Encryption private networks secure facilities Limited System Access by Alvaro E. Escobar 28
Biometrics n User Control of Personal Data : – – Allow user un-enrollment (voluntarily) Allow user view, correct and update data n Disclosure, Auditing and Accountability: – – Explain system purpose Third party auditing by Alvaro E. Escobar 29
