Claims19
A method for matching transactions against a known database of records comprising the steps of:
- accepting a transaction record;
- accepting a plurality of known records;
- comparing each field as interest in the transaction record to the corresponding field in each of said known records;
- creating a positive match score for each field in each of said known records that is based on the comparison of the transaction record to the known record;
- summing the positive match scores for each of the fields for each of the known records;
- comparing the sum of the positive match scores for each of the known records to a first threshold;
- and
- declaring a match for the known record if said sum of the positive match scores for that known record exceeds the first threshold.

An apparatus for matching a transaction against a known database of records comprising:
- transaction reception unit that receives a transaction record;
- legacy record reception unit that receives a plurality of known records;
- and
- positive match field comparison unit that:
- compares each field of the transaction record to a corresponding field in one record of said plurality of known records and increments a first accumulator whenever the field in the transaction record matches the field in the one known record;
- and
- generates a record match indicator signal when the value stored in the first accumulator exceeds the value stored in a first threshold register.
