Abstract:
1. A method comprising: receiving a search record and a plurality of file records from a database with each file record being identified by a different file record identification (ID), wherein the search and file records each comprise a plurality of prints corresponding to fingers on a hand, and each print is identified by a finger number that indicates a position of the corresponding finger on the hand; for each of at least some of the plurality prints in the search record, performing a search by comparing the print to the print in the file records having the same finger number and generating a corresponding sorted respondent list for the finger number comprising a portion of the plurality of file records, with each file record on the list being associated with a match score; determining a set of parameters comprising: the number of prints from the search record for which a search was performed and the corresponding finger numbers for those prints for which the search was performed, a size of the database, an average match score for each file record ID in the respondent lists, any file record IDs that appear on multiple respondent lists, any match scores on the respondent lists determined to be a non-matching score that is less than a match score threshold; determining a set of features based on the set of parameters; for the file records in the respondent lists, calculating at least one record identification metric based on the set of features and the set of parameters, wherein the record identification metric indicates whether there is a match between the search record and the corresponding file record.
