Single Answer, Multiple Choice
Which characteristic is NOT evaluated by the biometric system performing a hand geometry scan?
- Ridge endings
- Width of the hand
- Width of the fingers
- Length of the fingers
A. Ridge endings
A biometric system performing a hand geometry scan will not evaluate the ridge endings on fingers. Ridge endings and bifurcations on fingers are evaluated by a fingerprint scan biometric system and not by a hand geometry scan biometric system.
A biometric system performing a hand geometry scan will identify characteristics, such as the shape of a person's hand and the length and width of the fingers and the hand, to authenticate a user. The system compares the attributes provided by a user to the reference records that were gathered during the enrollment phase. If the attributes match, the user is granted access. Hand geometry scan-based biometric systems can either use the mechanical or the image detection technique to authenticate user credentials. Both of the methods verify hand attributes of a user for authentication purposes.
