Biometric and Access Control
Biometric Security 101
There are three possible ways of proving one’s identity:
- Using something you possess (e.g. keys, badge, documentation)
- Using something you know (e.g. password, code, security question)
- Using an intrinsic identifying feature (e.g. fingerprint, face)
Biometrics are an example of the third type, using biological measurements to identify individuals. Typically, these measurements are derived from physical characteristics, such as irises, fingerprints, facial features, or even a person’s voice.
When used in a security application, biometrics are theoretically more secure than traditional passwords since detailed physical characteristics are unique to each person.
