What is Biometrics?
Automated method for recognizing individuals based on measurable biological and behavioral characteristics
Finger Print Recognition
Minutiae
Pattern Matching
Problems: sometimes unusable
Vascular Pattern Matching
LED infrared light
Fingers and back of hand
Not completely viable
Iris Recognition
Uses infrared light
Converts Images to vectors
Needs further development
Facial Recognition
Location and position of facial features
Dependent on background and lighting conditions
Voice Verification
Factors: pitch, intensity, quality and duration
Text dependent
Text independent
Problems: include background noise
Hand Geometry
Scan both sides of hand
Primarily used for verification
Not as accurate as other methods
Dynamic Signature
Factors: velocity, acceleration and speed
Mainly used for verification
Problems: forgers could reproduce
Retina Recognition
One of the most secure means of biometrics
Unique to each person
Unique to each eye
Problems: require effort on the part of subjects
Other Types
Keystroke
DNA
Commercial Applications
Computer login
Electronic Payment
ATMs
Record Protection
Government Applications
Passport control
Access Control
Forensic Applications
Missing Persons
Corpse identification
Criminal investigations
Type of Authentication
Authentication 1:1
Verification 1:N
Constraints on Biometrics
Typical “Constrained” Image
Constraints: Lighting Distance Pose Expression Time Lapse Occlusion
