Biometric authentication requires comparing a registered or enrolled biometric sample (biometric

template or identifier) against a newly captured biometric sample (for example, a fingerprint

captured during a login).

During Enrollment, a sample of the biometric trait is captured, processed by a computer, and

stored for later comparison.

Biometric recognition can be used in Identification mode, where the biometric system identifies

a person from the entire enrolled population by searching a database for a match based solely on

the biometric. For example, an entire database can be searched to verify a person has not applied

for entitlement benefits under two different names. This is sometimes called “one-to-many”

matching.

A system can also be used in Verification mode, where the biometric system authenticates a

person’s claimed identity from their previously enrolled pattern. This is also called “one-to-one”

matching. In most computer access or network access environments, verification mode would be

used. A user enters an account, user name, or inserts a token such as a smart card, but instead of

entering a password, a simple touch with a finger or a glance at a camera is enough to authenticate

the user.
