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.
