  • Slide 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
  • Slide 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
  • Slide 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*
  • Slide 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
  • Slide 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
  • Slide 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
  • Slide 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
