The verifier itself determines the identity of the supplicant in ________.

• A. Verification
• B. Identification
• C. Both A and B
• D. Neither A nor B

Answer: (B)

In identification, the system is trying to figure out who is presenting themselves by performing one-to-many matching against all enrolled identities. The verifier analyzes the input (biometric sample, token, etc.) and decides the actual user tied to that evidence, effectively determining the claimant’s identity. In verification, the user already provides a claimed identity, and the verifier only checks whether the supplied credentials match that specific identity, not who the user is in general. So the verifier determines the identity in identification.
