Biometrics Edit

A false non-match

  • happen[s] when the technology rejects a valid presented biometric. False nonmatches could mean that an authorized person is denied access to a place, where he or she is, in actuality, permitted.[3]

Overview Edit

In verification and positive identification systems, people can be denied access to some facility or resource as the result of a system’s failure to make a correct match. In negative identification systems, the result of a false nonmatch may be that a person is granted access to resources to which she should be denied. For example, if a person who has enrolled in a public benefits program under another identity is not correctly matched, she will succeed in gaining fraudulent access to benefits.

False non-matches occur because there is not a sufficiently strong similarity between an individual’s enrollment and trial templates, which could be caused by any number of conditions. For example, an individual’s biometric data may have changed as a result of aging or injury.
