The method involves acquisition of a data record including a set of fields by an acquisition device (3), and selecting matched records stored in a database (5), where the matched data records have fields correspond to fields of the acquired record. A field is compared with the corresponding field of the acquired record to define a discrete metric in three states in which one of the states corresponds to an identity. A matching of data is searched by finite automaton in which each transition corresponds to a state of the metric of a field, where the automaton has paired and not paired states. An independent claim is also included for a method for checking identity of a recipient of an electronic mail.
