What is the most critical characteristic of a biometric identifying system?

A.
Perceived intrusiveness

B.
Storage requirements

C.
Accuracy

D.
Reliability

Explanation:
The principle of biometrics is to use some unique characteristic to identify whether
the person is who they say they are. Biometrics works by matching or verifying a person’s unique
traits with stored data in two categories: physiological characteristics and those that are
behavioral. Physical indicators include iris, fingerprint, facial, or hand geometry. Behavior types
are usually voiceprints, keystroke dynamics and handwritten signatures. Most biometric
technologies require special hardware to convert analog measurements of signatures, voices, or
patterns of fingerprints and palm prints, to digital measurement, which computers can read.
The biggest characteristic and problem of biometric implementations today is the accuracy, we
must see the level of accuracy before buying a solution, because the technology is not perfect at
this time and it can be erroneous sometimes.
