Method of matching data and use in the verification of identity of a recipient of a mail

Abstract

A method of matching identification data comprising: acquisition of a data record comprising a plurality of fields; selection of matched records stored in a database, the data records having fields of type corresponding to the fields of the record acquired, the selection comprising for each record of the database: comparison of at least one field with the corresponding field of the record acquired, the comparison defining a discrete metric with at least three states of which a first state corresponds to an identity; and search for the match by traversal of a finite automaton in which each transition corresponds to at least one state of the comparison metric for at least one field, the finite automaton having at least two final states: matched and unmatched.
