Abstract
A machine and method of reducing duplicate transmission data employs one more more digests to track field/value pairs that have previously been distributed. Each digest contains a record table and a segment table. The record table includes anonymous identifier records, each of which contain an anonymous identifier and one or more indexes into the segment table. The segment table comprises an array of every existing data field/value pair. Before distribution of update data, each record is matched to an anonymous identifier record in the record table. The segment values in the prospective distribution record are compared to the digest's anonymous identifier record, used to determine which data has already been distributed, and thus will be suppressed in the distribution.
