FRSC 2600: CH 7 - BIOMETRICS EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED LATEST
UPDATE GRADED A++
Biometrics
form of access control that accurately and efficiently identifies a human (uses
physiological and behavior traits)
2 Functions of Biometrics
1. Matching/verification
2. Overall identification
Biometric matching/verification
identifies someone out of a crowd by scanning select biometric characteristics
Biometric identification
access-controlled systems create and store databases of biological traits and compare
them to the individual attempting to gain entry to device/facility
Physiological Biometrics
- fingerprints
- hand scans (similar to vein scans, also looks at joints/bones)
- iris scans (colored part of eye)
- retina scans (blood vessels deeper into the eye)
- facial scans (least accurate)
Behavioral Biometrics
, *less accurate than physiological
- handwriting (strokes, arches, pressure)
- voice recognition (dynamics/pitch)
- keystroke recognition (speeds/pressures)
- gait recognition (posture/step length/speed/foot position)
Enrollment
- captures a person's biometric data and stores in database for later use
- once info completes its run through model, feature extraction begins
Extraction
- finds patterns in traits extracted by the sensor through math equations
- systems have different equations/algorithims for unique characteristics
- most complex and important components!
Template module
- saves all raw data produced by feature extraction and puts it into simple format
- compares a user to rest of data for determining matches
Iris Biometrics
- intricate muscle patterns in iris construction is unique
- unchanged through lifetime
- started in 1950s
- FBI working on IrisCode
Facial Recognition
- analyzes variety of features with clear image
- system normalizes image
