Biometric Authentication Security: Fingerprint, Face ID, and Beyond
Understanding Biometric Authentication Biometric authentication uses unique physical or behavioral characteristics to verify identity. Unlike passwords, which can be forgotten, stolen, or guessed, biometric identifiers are inherently personal and difficult to duplicate. This fundamental advantage has made biometric authentication increasingly popular in consumer and enterprise security. The term “biometric” comes from “bio” (life) and “metric” (measurement). Biometric systems measure and analyze unique characteristics that remain relatively constant throughout life. These characteristics can be physical (fingerprints, facial features, iris patterns) or behavioral (voiceprints, typing patterns, gait patterns). ...
