Biometric authentication leverages unique physiological or behavioral characteristics, such as fingerprints, facial recognition, or iris scans, to verify a user’s identity. It is considered one of the most secure methods of authentication because these traits are nearly impossible to replicate or steal. In environments with high sensitivity, such as financial institutions or military systems, biometric systems are deployed due to their resistance to attacks like phishing or social engineering. Unlike passwords, which can be guessed or stolen, biometrics are inherently tied to the individual, providing a non-repudiable form of identity verification. Why Other Options Are Incorrect: 1. Password-based authentication: Easily compromised through brute force, phishing, or poor user practices. 2. Two-Factor Authentication (2FA): Adds a layer of security but relies on secondary methods like SMS, which can be intercepted. 3. Knowledge-based authentication (KBA): Relies on answers to personal questions, which can be guessed or obtained via social engineering. 4. Token-based authentication: Secure but subject to loss or theft of the physical token. While each method offers varying levels of security, biometrics provides the highest assurance against impersonation and fraud.
