There are different types of biometric systems in the industry today. Some makeauthentication decisions based on behavior and some make authentication decisionsbased on physical attributes. Which of the following is the best description oftheir differences?

A.
A system that uses physical attributes provides more accuracy than one that uses behavior attributes.

B.
A system that uses behavior attributes provides more accuracy than one that uses physical attributes.

C.
A fingerprint system is an example of a physical attribute and an iris system is an example of a behavior system.

D.
A voice print system is an example of a behavior and signature dynamics is anexample of a physical attribute.

Explanation:
A biometric system can make authentication decisions based on an individualsbehavior, as in signature dynamics and voice prints, but these can change over timeand possibly be forged. Biometric systems that base authentication decisions onphysical attributes (iris, retina, fingerprint) provide more accuracy, because theydo not change as often and are harder to impersonate.
