WebThe false match rate (FMR) is the rate at which a biometric process mismatches biometric signals from two distinct individuals as coming from the same individual. … WebThe FAR (false acceptance rate) is the probability of cases for which a biometric system fallaciously authorizes an unauthorized person. It happens when a biometric system, solution or application inaccurately matches a biometric input with a stored template, fallaciously returning a match and granting access to an unauthorized person.
