Two types of biometrics◦physiological

◦behavioral

Types are used for:◦identification

◦verification

Specific Types Specific Types

FingerprintFace RecognitionIris VerificationVoice RecognitionHandwriting

FingerprintFingerprintLargest market of biometricsOne of the types that predates computersLooks are the friction ridges on finger tips

◦1870's - classifications of loops, whorls, arches

and tents

◦Matching points

Main original use in law and job applicants◦Other ex.: authentication

Optical sensors vs. Swipe

Face RecognitionFace RecognitionOldest identification mechanismsPhoto IDs are always neededExamining the picture

◦Important second form of ID◦Though more importance switches to

authenticity of the ID cardSystem are used, but many negatives

◦Camera position, “Neutral expression”, Deception

◦Positive can do done without user knowledge, but privacy concerns

Iris VerificationIris Verification

Iris is measurably unique

◦easy to detect, doesn't wear out, protectedRandomness & number of degrees of freedomPhenotypicSimpler processing technique than fingerprintsAdvantages: Technically greater certainty of

verification of a person, non-invasiveNegative views: More user cooperation, attempt at

fraud

Voice RecognitionVoice Recognition

Many subproblems: environment, text

dependent system, identify from large set

or verify speakers, real timeSimple technical integrationFraud potential

Handwriting/SignatureHandwriting/Signature

Another mechanism to predate computer

technologyExamining writing vs. using a signature

tabletReliability? Lies in the system/verifier

Performance & FactorsPerformance & Factors

User Factors◦Enrolling people◦Aging◦Acceptance

Education Privacy

Human IDHuman ID Lead by Defense Advanced

Research Projects Agency

(DARPA) Automated biometric

identification technologies to

detect, recognize and identify

humans at great distances protection of homeland

security Face recognition, Gait

classification, Iris Recognition Expected range 500 ft.

LG LP3800 Cell PhoneLG LP3800 Cell Phone

First mobile phone

with fingerprint readerLG phone to be

securely locked, yet

easily unlocked by the

proper personAvoids problems

FBI DatabaseFBI Database

Initiatives to group database of biometrics beyond

digital images of faces, fingerprints and palm patterns Already going on:

◦DOD has data on detainees, citizens and foreigners

◦Pentagon keeps DNA samples 100,000 requests come in daily 55% related to civilian background checks Matching standards of other countries Biggest concern = Privacy
