True or False: Using biometrics during a digital test is a fail-safe method to ensure the candidate is the person taking the test.

• A. True
• B. False
• C. Not sure
• D. Only sometimes

Answer: (B)

Biometrics can help verify who is taking a test, but they’re not fail-safe. No biometric system—fingerprint, facial recognition, iris scan, or voice—has zero error. They come with false accept rates (an imposter being recognized as you) and false rejection rates (the real person being denied). Attackers can spoof or trick the system with photos, masks, or recordings, and even with liveness checks there are ways to bypass or defeat them. Performance also depends on device quality, lighting, and other environmental factors, which means accuracy isn’t guaranteed across all testing scenarios.

Because of these limitations, biometric verification should be one part of a broader, multi-layered approach to identity verification in digital testing. Combining biometrics with other controls—like verified photo ID, remote proctoring, device and location checks, and continuous monitoring—reduces risk but still cannot promise perfect assurance that the person taking the test is the registered candidate.
