  1. Biometrics Group 3 Tina, Joel, Mark, Jerrod

  2. Biometrics Defined • Automated methods or recognizing a person based on a physiological and behavioral characteristics • Derived from the Greek words bios (life) and metron (to measure)

  3. A Little History • First known example was in China in the 14th century in the form of fingerprinting • Chinese merchants began stamping children’s palm prints and footprints in order to distinguish the young children from one another

  4. “Bertillonage” (a method of body measure) • Started in 1890’s • Alphonse Bertillion developed “Bertillonage” in order to fix the problem of identifying criminals. • Thus, turning Biometrics into a distinct field of study

  5. How does it work? • Step 1 = Capture • A physical or behavioral sample is captured by system during enrolment • Step 2 = Extraction • Unique data are extracted from the sample and a template is created; unique features are then extracted by system and then turned into mathematical code; template is then stored

  6. Step 3 = Comparison • Template is then compared to new sample; computer algorithm normalizes captured biometric signature; biometric data are then stored as the biometric template for that person • Step 4 = Match / Non-match • System decides whether the features extracted from the new sample are a match or a non-match with the template; if so, the person’s identity is confirmed

  8. PHYSICAL BEHAVORIAL Types of Biometrics Behavioral biometrics are generally used for verification while physical biometrics can be used for either identification or verification.

  9. Bertillonage - measure body lengths (no longer used) Fingerprint – analyzing fingertip patterns Facial Recognition – measuring facial characteristics Hand Geometry – measuring the shape of the hand Iris Scan - analyzing features of colored ring of the eye Retinal Scan – analyzing blood vessels in the eye Vascular Patterns – analyzing vein patterns DNA – analyzing genetic makeup PHYSICAL

  10. BEHAVORIAL • Speaker Recognition – analyzing vocal behavior • Signature – analyzing signature dynamics • Keystroke – measuring the time spacing of typed words

  11. Verification Identification Two Major Uses

  12. BIOMETRIC FUTURE • The future of biometrics holds great promise for law enforcement applications, as well for private industry uses.
