Which of the following biometrics has the highest reliability and lowest false-acceptance rate (FAR)

Which of the following biometrics has the highest reliability and lowest false-acceptance rate
(FAR)?

A.
Palm scan

B.
Face recognition

C.
Retina scan

D.
Hand geometry

Explanation:

Retina scan uses optical technology to map the capillary pattern of an eye’s retinA. This is highly
reliable and has the lowest false-acceptance rate (FAR) among the current biometric methods.
Use of palm scanning entails placing a hand on a scannerwhere a palm’s physical characteristics
are captured. Hand geometry, one of the oldest techniques, measures the physical characteristics
of the user’s hands and fingers from a three dimensional perspective. The palm and hand
biometric techniques lackuniqueness in the geometry datA. In face biometrics, a reader analyzes
the images captured for general facial characteristics. Though considered a natural and friendly
biometric, the main disadvantage of face recognition is the lack of uniqueness, which means that
people looking alike can fool the device.
