What is a major advantage of biometrics as a means of interaction with digital devices?

• A. Privacy concerns
• B. Hygiene concerns when using fingerprint sensors
• C. It is slow
• D. Very high security

Answer: (D)

Biometric authentication relies on unique physical traits, such as a fingerprint, iris pattern, or facial features, to verify identity. Because these traits are specific to each person and not easily guessed or copied, using biometrics provides a higher level of security than traditional methods like passwords or PINs. You don’t rely on something you know or have that could be stolen or reused; instead, access is granted only when the live trait matches the stored template, which makes unauthorized access much harder. Of course, there are trade-offs to consider, like privacy and potential spoofing risks, but the standout advantage is the strong security.
