biometrics in security

Biometrics in security refers to using unique physical or behavioral traits—such as fingerprints, facial features, or voice patterns—to verify identities. This technology ensures that only authorized individuals can access systems or locations. Because these traits are hard to forge or guess, biometrics provides a reliable and fast way to enhance security. Common examples include fingerprint scanners on phones, facial recognition at airports, and voice authentication for banking. Overall, biometrics offers a convenient and robust method of identity verification, reducing the risk of unauthorized access compared to traditional passwords or PINs.
