You have decided to implement biometrics as part of your security system. Before purchasing a locking system that uses biometrics to control access to secure areas, you need to decide what will be used to authenticate users. Which of the following options relies solely on biometric authentication?
A.
Username and password.
B.
Fingerprints, retinal scans, PIN numbers, and facial characteristics.
C.
Voice patterns, fingerprints, and retinal scans.
D.
Strong passwords, PIN numbers, and digital imaging.
Explanation:
Biometric systems are those that use some kind of unique biological identifier to identify a person. Some of these unique identifiers include fingerprints, patterns on the retina, and handprints, and DNA scanners, and they can be used as part of the access control mechanisms. Usernames, passwords and PINs are not apart of biometrics.
