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. A biometric system can make authentication decisions basedon an individual’s behavior, as in signature dynamics, but these can change overtime and possibly be forged. Biometric systems that base authentication decisions onphysical attributes (such as iris, retina, or fingerprint) provide more accuracy,because physical attributes typically don’t change, absent some disfiguring injury,and are harder to impersonate.
