Biometrics 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:
- Facial recognition
- Retina or Iris patterns
- Voice recognition
- Pulse / ECG
- Gestures / tap pattern (behavioural)
