Abstract: The present disclosure concerns a method of identifying a biometric record of an individual in a database (108) having a plurality of biometric records, the method involving: during a training phase: applying by a processing device a matching operation to determine scores for a similarity between at least one training biometric sample of each of a plurality of training records and at least one probe sample; based on said scores, determining a threshold value (STH,MTH); and during an identification phase: evaluating at least one reference biometric sample of each of the records of said database to determine a parameter value for each record; selecting a subset of said records by comparing each of said parameter values with said threshold value; and applying a matching operation to the selected records to determine whether an input biometric sample matches a reference biometric sample of one of said selected records.
