Corrected Question:
Which of the following biometric security measures compares the length of each finger, the translucence of fingertips, and the webbing between fingers against stored data to verify users' identities?
A) Hand geometry
B) Fingerprint recognition
C) Vein analysis
D) Palm prints
Answer:
A. Hand geometry
Step-by-step explanation:
The hand geometry recognition is one of the biometric security meaures and it takes advantage of the structure of the palm and fingers by measuring certain features of the hand such as;
i) width of the finger at various places,
ii) length of each of the fingers,
iii) palm area thickness
iv) translucence of the fingertips
v) webbing between fingers - syndactyly.
There are enough information that can be got from the hand geometry in order to verify the identity of a user.
The hand geometry scanner takes a full 3-D scan image of the hand. Devices can then compare the details that are got from the image of the hand with those stored on the database for verification purposes.
