What does biometric access control utilize for user authentication?

• A. Passwords
• B. Physical characteristics
• C. Security tokens
• D. PIN numbers

Answer: (B)

Biometric access control utilizes physical characteristics for user authentication, making it a highly secure method for verifying individuals' identities. This approach relies on unique traits such as fingerprints, facial recognition, retina patterns, or voice recognition. These physical attributes are inherent to the user, making them difficult to replicate or steal compared to traditional authentication methods like passwords or PIN numbers. Using biometric data ensures that only the individual with the corresponding physical characteristic can gain access, enhancing security significantly. Unlike passwords or security tokens, which can be forgotten or lost, biometric traits are always with the individual, ensuring a high level of convenience without compromising security. The technology behind biometric systems is designed to analyze and assess these unique traits in real-time, allowing for quick and efficient authentication.
