Why are biometric systems considered more accurate than many of the other typesof authentication technologies in use today?

A.
They are less accurate

B.
They are harder to circumvent than other mechanisms

C.
Biometric systems achieve high CER values

D.
They have less Type I errors than Type II errors

Explanation:
Biometrics verifies an individual’s identity by analyzing a unique personalattribute or behavior, which is one of the most effective and accurate methods ofverifying identification. Biometrics is a very sophisticated technology; thus, it ismuch more expensive and complex than the other types of identity verificationprocesses. A biometric system can make authentication decisions based on anindividual’s behavior, as in signature dynamics, but these can change over time andpossibly be forged. Biometric systems that base authentication decisions on physicalattributes (such as iris, retina, or fingerprint) provide more accuracy, becausephysical attributes typically don’t change, absent some disfiguring injury, and areharder to impersonate.CER and Type I and II errors pertain only to biometric systems and not to any otherauthentication technologies.
