Abstract
A method of verifying an input biometric identifier against a reference biometric identifier is disclosed in this specification. The method comprises evaluating the input biometric identifier relative to a group (the ‘cohort’) to improve verification accuracy. Up to three matching scores are used to determine a verification probability for the input biometric identifier. The three matching scores measure the similarity of the input biometric identifier to the biometric identifiers of the cohort, the similarity of the reference biometric identifier to the biometric identifiers of the cohort and the similarity of the input biometric identifier to the reference biometric identifier.
