  9. Biometrics • Definition • Biometrics is the science of verifying and establishing the identity of an individual through physiological features or behavioral traits • Examples • Physical Biometrics • Fingerprint, Hand Geometry,Iris,Face • Measurement Biometric • Dependent on environment/interaction • Behavioral Biometrics • Handwriting, Signature, Speech, Gait • Performance/Temporal biometric • Dependent on state of mind • Chemical Biometrics • DNA, blood-glucose

  10. Conventional Security Measures • Possession or Token Based • Passport, IDs, Keys • License ,Smart cards,Swipe cards, Credit Cards • Knowledge Based • Username/password • PIN • Combination of possession and knowledge • ATM • Disadvantages of Conventional Measures • Do not authenticate the user • Tokens can be lost or misused • Passwords can be forgotten • Multiple tokens and passwords difficult to manage • Repudiation

  11. Need for biometrics • Reliable authentication and authorization • Billions of dollars are lost in identity theft and fraud • Common security measures authenticate the token or password and not the user. • Repudiation problems cannot be resolved even in the face of well documented audit trails. • Identity management • Managing multiple tokens, badges, usernames and passwords are cumbersome • Maintaining such personally • Biometrics cannot be lost, forgotten or stolen*

  12. Characteristics of Biometrics • Universality • Each person should have the biometric • Uniqueness • Any two persons should have distinctive characteristics • Permanence • Characteristic should be invariant over time • Collectability • Characteristic should be easy to acquire • Acceptability • Is non-intrusive and accepted by a large population • Non repudiation • User cannot deny having accessed the system

  13. The Field of Biometrics • Biometrics grew out of different fields • Speaker ID : Signal processing • Face Recognition: Computer Vision • Fingerprints : Forensics • Biometrics is the confluence of several disciplines • Sensors: electrical and mechanical engineering • Pattern recognition, probability and statistics • Image processing and computer vision • Signal processing • Algorithms and databases

  14. Uses of Biometric Systems • Physical access control • Airports, Banks, Industry • Logical access control • Computer/network logon, e-commerce • Preventing identity fraud • Social security (double dipping), Immigration, Border Control • Information assurance • Audit trails, Biometric cryptography protocols • Securing pervasive environments

  15. Aspects of a Biometric Systems • Sensor and devices • Types of sensors • Electrical and mechanical design • Feature representation and matching • Enhancement, preprocessing • Developing invariant representations • Developing matching algorithms • Evaluation • Testing • System Issues • Large Scale databases • Securing Biometric Systems • Ethical, Legal and Privacy Issues • Ergonomics, usability
