2. Contents Introduction Specific Types of Biometrics Examples Personal Experience Questions

3. Introduction Greek meaning – life and measure technical solution to authentication Certain techniques predate computers Modernized in the 1960's, 1980's systems went live

4. Introduction Continued Two types of biometrics ◦physiological ◦behavioral Types are used for: ◦identification ◦verification

5. Specific Types Fingerprint Face Recognition Iris Verification Voice Recognition Handwriting

6. Fingerprint Largest market of biometrics One of the types that predates computers Looks 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

7. Face Recognition Oldest identification mechanisms Photo IDs are always needed Examining the picture ◦Important second form of ID ◦Though more importance switches to authenticity of the ID card System are used, but many negatives ◦Camera position, “Neutral expression”, Deception ◦Positive can do done without user knowledge, but privacy concerns

8. Iris Verification Iris is measurably unique ◦easy to detect, doesn't wear out, protected Randomness & number of degrees of freedom Phenotypic Simpler processing technique than fingerprints Advantages: Technically greater certainty of verification of a person, non-invasive Negative views: More user cooperation, attempt at fraud

9. Voice Recognition Many subproblems: environment, text dependent system, identify from large set or verify speakers, real time Simple technical integration Fraud potential

10. Handwriting/Signature Another mechanism to predate computer technology Examining writing vs. using a signature tablet Reliability? Lies in the system/verifier

11. Performance & Factors Performance ◦False Acceptance Rates ◦False Reject Rates User Factors ◦Enrolling people ◦Aging ◦Acceptance  Education  Privacy

12. Human 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.

13. LG LP3800 Cell Phone First mobile phone with fingerprint reader LG phone to be securely locked, yet easily unlocked by the proper person Avoids problems

14. FBI 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

15. Personal Experience Fingerprinting Signature & Facial Recognition ◦credit cards/debit cards
