The present invention relates to a method of fusing at least two different candidate lists into a single candidate list, said at least two different candidate lists being generated by matching biometric data captured from an individual to be identified and biometric data enrolled from candidates to calculate match scores of candidates and ranking said match scores, the method comprising steps of:



normalizing the match scores of the candidates of said at least two different candidate lists;
ranking at least part of the candidates of said at least two different candidate lists in a single candidate list according to said normalized match scores to fuse said at least two different candidate lists;
identifying at least one candidate belonging to multiple lists of said at least two different candidate lists; and
raising said identified at least one candidate's rank in said single candidate list.
