Biometric security is the use of biometric data for identification, access control, and authentication. Cameras or fingerprint readers scan biometric data and compare it to information held in a database. Access is granted if the two sets of data match and identity is authenticated.

Biometric security is more robust and more difficult to crack than other authentication methods such as username-password combinations. The use of biometric security is growing rapidly worldwide. Biometric security systems are mainly used to secure highly sensitive facilities and systems.
Types of biometric security:
- Facial recognition
- Fingerprint scanning
- Iris or retina recognition
- Voice recognition
- Finger and hand vein recognition
