1. A method of identifying a biometric record of an individual in a database (108), the database comprising a plurality of biometric records, the method comprising:

  • during a training phase;

    applying by a processing device (302) 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 by said processing device 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.
