CISSP · Question #222

During a fingerprint verification process, which of the following is used to verify identity and authentication?

The correct answer is D. A template of minutiae is compared with a stored template. Fingerprint verification relies on extracting unique ridge endpoints and bifurcations called minutiae, which are compared against a previously enrolled template to authenticate identity.

Why each option

Fingerprint verification relies on extracting unique ridge endpoints and bifurcations called minutiae, which are compared against a previously enrolled template to authenticate identity.

AA pressure value is compared with a stored template

Pressure values are not a standard fingerprint biometric matching metric; fingerprint sensors may use pressure to detect liveness but do not compare pressure as the identity verification mechanism.

BSets of digits are matched with stored values

Matching sets of digits describes PIN-based or numeric token authentication, not biometric fingerprint verification, which is pattern-based rather than digit-based.

CA hash table is matched to a database of stored value

Hash tables matching to a database describes a cryptographic or password authentication mechanism, not the minutiae-based template comparison used in fingerprint biometrics.

DA template of minutiae is compared with a stored templateCorrect

Fingerprint biometric systems work by extracting minutiae points - specific ridge endings, bifurcations, and other unique features from a fingerprint scan - and encoding them into a template. During verification, the live scan's minutiae template is compared against the stored enrollment template using a matching algorithm, and if the similarity score exceeds a defined threshold, authentication is granted. This is the standard biometric matching process used in all major fingerprint recognition systems.
