A system for managing opt-out instructions includes a global opt-out service and opt-out store in communication with regional subsystems. The opt-out service maintains a global opt-out store database of consumers for whom opt-out instructions have been received. The opt-out store includes no personal data, but instead contains only anonymized data. Before consumer data is utilized, an anonymized identifier is created by a regional data anonymizer and transmitted to the opt-out store. The opt-out instructions are applied by searching for a match in the opt-out store for a matching anonymized identifier. In this manner, the system may comply with privacy laws and regulations concerning the transmission of personal data outside of a region, while still providing a global opt-out service.

Anonymized global opt-out

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.
