Biometrics

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:

• 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
