What is Biometric authentication?

Biometric authentication is a method of verifying the identity of an individual using their unique physical or behavioral characteristics. Biometric authentication is a type of authentication that can be used to replace or supplement traditional authentication methods such as passwords, PINs, or security tokens.

Biometric authentication systems capture and analyze various biometric traits such as facial features, fingerprints, iris patterns, voice, hand geometry, and others to match them against stored templates or reference data. When a user attempts to access a system or service, the biometric authentication system compares the captured biometric data against the stored templates to determine if there is a match. If the system confirms a match, the user is granted access. If the system does not find a match, the user is denied access.

Biometric authentication is considered to be more secure than traditional authentication methods because biometric traits are unique to each individual and difficult to forge or steal. However, biometric authentication systems have their own set of security and privacy concerns, such as the risk of biometric data being stolen or compromised. As such, it is important to ensure that biometric authentication systems are designed and implemented with proper security and privacy controls.
