  1. Nithin Reddy CS 265, Mark Stamp 05 April 2004 Overview of Biometrics with a Case Study in Hand Geometry

  2. Bertillonage • The first biometric system • Developed in the 19th Century • Used in Prisons • Took a long time (60 minutes) to collect measurements

  3. Biometrics – Overview • the measurement of people by computers to provide verification and/or identification • Verification – checking that an individual is who she says she is • Identification – determining who an individual is • Depending on use doesn't need to uniquely categorize every person

  4. Biometrics – Process • Enrollment phase • Digital representation • Template Creation and Storage • Recognition phase • Digital representation • Comparison using Pattern matching

  5. Biometrics – Process

  6. Biometrics – Performance • Accuracy • False matches – letting a bad guy in • False nonmatches – keeping a good guy out • Speed • Storage size of Templates

  7. Biometrics – Acceptance • Easy-to-use • Safe – perceived safety, not actual safety • Private – should not be thought of as shared • Fingerprint information is used by government, users might assume that big brother is watching them

  8. Types of Biometrics

  9. Hand Geometry • Most common type of biometric system • measurements include the shape of the hand and the length, width, and height of the fingers • Used for verification, because human hand is not unique • Access Control and User Tracking

  10. Hand Reader

  11. Using the Hand Reader • Enrollment • User ID is given out • template is generated • Recognition • ID number is entered • Hand is compared with template

  12. Hand Geometry Analysis • Advantages • Quick: 5 second recognition time, 1 minute enrollment time • High Acceptance rate • Disadvantages • Can't use on young / old people • Jewelry can interfere
