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.
