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)
The Identification Process
- A person’s unique characteristic is captured and stored in a database
- When authentication is needed, a new record is captured
- The new record is compared to the stored record in the database
- If the data matches, the identity is confirmed
