Verification vs. Identification Do you know me? • Verification – – One to one Claim identity Quick Are you who you claim to be? • Identification – One to many – Search entire database – Do I know who you are?

Hand Geometry and Templates

What Is Hand Geometry? • Unique size and shape of hand • Not finger or palm prints • Oldest biometric – 2 D Identimat (1976) • Most widely used biometric – More than 25, 000 installed

Template Creation • Enrollment • Over 90 distinct measurements – – Length Width Thickness Surface area • Average of three hand placements

How it Works

Lights and Cameras • Low level infra-red light • Camera chip – Records image – Image appears as black shadow • Mirror/reflector determine hand position – Measure length, width, surface area – Measure height with side mirror

The Way We See It User’s hand Hand reader Light Source / Flashlight Hand image/shadow

Verify and Score! • Compare stored template with current placement • “Score” – Difference between memory & placement – Successful verification – Lower score means closer match

Enrollment

Enrollment • Adds templates to Hand. Punch • Hand placement – Key to successful enrollment – Bad placements produce verification problems

Hand Placement • Flat hand • Fingers closed around web finger pin • LED lights on top panel extinguish • Camera records digital image when all finger-pin lights out Web finger pin

Rings and Fingernails • Jewelry may be worn • Stones must face upwards • Long/false fingernails – Algorithm looks for curvature of finger – Curvature indicates change between finger and nail Curvature of finger

Command Mode A means of programming the Hand. Punch which can be done only by a Hand. Punch supervisor
