Which of the following is an example of a biometric authentication method?

• A. Password entry
• B. TOKENs
• C. Fingerprint scanning
• D. Smart card access

Answer: (C)

Biometric authentication methods utilize unique physical characteristics of individuals to verify their identity. Fingerprint scanning is a prime example of this type of method because it relies on each person's distinct fingerprint patterns for authentication. This form of authentication is widely used due to its effectiveness and difficulty to replicate, making it a strong security measure. In contrast, password entry, TOKENs, and smart card access represent different forms of authentication that rely on something the user knows (a password), something they have (a TOKEN or smart card), rather than something they are (like fingerprints). These methods do not use physiological attributes for authentication, which is a key aspect of biometric systems.
