Benefits
•
Simple to use – a biometric sample is all that is required.
Drawbacks
•
Can be slow – depends on number of templates to match against and the efficiency of the algorithm
used.
•
Higher chance of false rejections and false acceptances
•
Only a single factor on which authentication will be based.
1:1 (ONE-TO-ONE) MATCHING
One-to-One matching is another way of referring to the process of verifying that the provided biometric
sample matches a single, specified identity. Because we know which identity we’re looking for, we don’t
need to match against every stored biometric – we take the provided sample and compare it directly to
the biometrics linked to the specified identity. The result will be the acceptance or refusal of the identity
claim.
The term ‘verification’ was defined in a previous draft of the Harmonized Biometric Vocabulary document
as a ‘one -to- one process of comparing a submitted biometric sample (…) against the biometric reference
template (…) of a single enrolee (…) whose identity is being claimed, to determine whether it matches the
enrolee’s template’. Contrast with identification (…)”.
Benefits
•
One-to-One matches are much faster than One-to-Many matches.
•
Because we know which biometric template the provided sample needs to match, we can lower the
matching threshold to allow a better chance of a match being detected.
•
Significantly lower chance of false acceptances and false rejections.
•
Multi-factor authentication offers better security with each additional factor.
Drawbacks
•
The person may forget or lose a card
•
The person may forget a PIN code
MULTI-FACTOR AUTHENT ICATION
Multi-factor authentication ( MFA ) is an approach to authentication which requires the presentation of
two or more authentication factors of the following kind:
•
A knowledge factor: something only the user knows , like a PIN or password.
•
A possession factor: something the user has , like an ID card or NFC tag.
•
An inherence factor: something the user is, a biometric characteristic such as a fingerprint.
A one-to-one matching system based on multi-factor authentication significantly increases the security of
your system while lowering false acceptance and rejection rates. Presenting a smart card to a device
capable of reading it, for instance, immediately satisfies the possession factor and tells the system exactly
which identity we wish to confirm. By placing a finger on the biometric reader, the inherence factor is met
and a 1:1 match can be don
e. We now have two levels on which we can authenticate the person’s identity:
•
Has the person presented a recognized card?
•
Does the fingerprint match the identity linked to the card?
