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 childrens palm
  prints and footprints in order to distinguish the
  young children from one another

4

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

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 persons identity
  is confirmed

Types of Biometrics

• PHYSICAL

• BEHAVORIAL

Behavioral biometrics are generally used for
verification while physical biometrics can be
used for either identification or verification.
10
PHYSICAL

• 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

11
BEHAVORIAL

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

12
Two Major Uses

• Verification

• Identification

BIOMETRIC FUTURE

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