Biometrics

Biometrics iris scannerBiometrics is a term given to the calculation and use of the measurable physical characteristics of a human.

Biometrics is becoming an increasingly popular form of authentication to gain access to restricted computer systems.  To achieve this, a person is uniquely identified by examining one or more biological traits or behavioural characteristics.  This can be instead of, or in conjunction with, a traditional password or pin.

Characteristics for biometric authentication can include:

  • Fingerprints
  • Facial recognition
  • Retina or Iris patterns
  • Voice recognition
  • DNA
  • Pulse / ECG
  • Gestures / tap pattern (behavioural)

The Identification Process

  1. A person’s unique characteristic is captured and stored in a database
  2. When authentication is needed, a new record is captured
  3. The new record is compared to the stored record in the database
  4. If the data matches, the identity is confirmed
