Which statement describes a negative aspect of biometrics?

• A. It is expensive to implement and maintain
• B. It is secure
• C. It is easy to copy
• D. It requires no hardware

Answer: (A)

Evaluating the drawbacks of using biometrics, cost stands out as a real practical hurdle. Implementing biometric authentication requires hardware such as scanners or cameras, plus software for enrollment, template storage, and matching. There are ongoing expenses too—maintenance of devices, software updates, dealing with faulty sensors, and potential scalability costs as the user base grows. All of this can make biometrics expensive to set up and keep running, which is a clear downside compared to cheaper methods like passwords or tokens. The other statements describe aspects that aren’t drawbacks in the same way. Biometrics being secure is a benefit, not a downside. The idea that biometrics is easy to copy is not generally true and depends on protections like liveness checks and anti-spoofing measures. The claim that biometrics requires no hardware is simply incorrect because sensors are essential to capture the biometric data.
