Which measures reflect the effectiveness of a biometric authentication system?
False Acceptance Rate (FAR) The FAR is the frequency that a non authorized person is accepted as authorized. Because a false acceptance can often lead to damages, FAR is generally a security relevant measure. FAR is a non-stationary statistical quantity which does not only show a personal correlation, it can even be determined for each individual biometric characteristic (called personal FAR). False Rejection Rate (FRR) The FRR is the frequency that an authorized person is rejected access. FRR is generally thought of as a comfort criteria, because a false rejection is most of all annoying. FRR is a non-stationary statistical quantity which does not only show a strong personal correlation, it can even be determined for each individual biometric characteristic (called personal FRR). Failure To Enrol rate (FTE, also FER) The FER is the proportion of people who fail to be enroled successfully.
