Biometrics refers to the use of measurable physical or behavioral traits, including fingerprints, facial geometry, iris patterns, voiceprints, and individual user behavior, for the purposes of identity verification and controlling access, for example, to digital accounts or physical locations. By analyzing these unique user characteristics, biometric systems provide a powerful foundation for secure and user-friendly authentication.
Use case/ examples for biometrics
Mobile device security: Securing access to smartphones and mobile apps by using biometric authentication, like fingerprint or facial recognition, to prevent unauthorized use - for example, requiring the use of Face ID or fingerprint scan to unlock a phone or app, or authorizing mobile banking or digital wallet transactions via re-authentication using biometrics.
Airport security: Verifying passenger identity at airports through biometric matching, typically facial recognition, to streamline security lines and airplane boarding while reducing threats. Examples include scanning a traveler's face at a TSA checkpoint to match against passport records, or replacing manual boarding pass and ID checks with facial recognition at the gate.
