Biometric Authentication Techniques

Biometric authentication techniques are methods that use unique physical or behavioral traits to verify a person's identity. Common examples include fingerprint scanning, facial recognition, iris scanning, and voice recognition. These technologies capture specific features of an individual and compare them to stored data to confirm identity. Biometric authentication is often used in security systems, smartphones, and access control, providing a secure alternative to traditional passwords, as traits like fingerprints are hard to replicate and provide a personal layer of security.
