BiometricsBiometrics

Definition:“Automated measurement of Physiological and/or behavioral characteristics to determine or authenticate identity”

by Alvaro E. Escobar 4

BiometricsBiometrics

“Automated measurement”No human involvement.Comparison takes place in Real-Time.

DNA is not a Biometric

by Alvaro E. Escobar 5

BiometricsBiometrics

“Physiological and/or behavioral characteristics“

1. Behavioral:User speaks.

Types on a keyboard.Signs name.

2. Physiological:Fingerprint

“determine or authenticate identity” Identification Systems:

Who am I?Determine Identity

Verification Systems:

Am I who I claim to be?Authenticate Identity

BiometricsBiometrics

“determine or authenticate identity” Verification Systems (cont):

More accurate.Less expensive.

Faster.More limited in function.

Requires more effort by user.

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.

BiometricsBiometrics

Hand scan: measures the top and side of the hand, not the Palm.

Hand Geometry.Most widely used technique for physical

access.INSpass system

Voice scan: Measures the sound waves of human speech.

user talks to a microphone a passphrase.

Voice print is compared to a previous one

BiometricsBiometrics

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

BiometricsBiometrics

Signature scan: Measures speed, pressure, stroke order an image of signature.

Non-repudiation

BiometricsBiometrics

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.
