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.
