Claim 23:
24. A method comprising:
receiving, at a private data system, at a first enterprise, that includes a private database, a first query message sent from a second enterprise comprising a first set of query attributes representing a first subject;
transmitting the first set of query attributes representing the first subject to a reference data system to verify an identity of the first subject, wherein the reference data system includes a reference database which contains a plurality of reference data records that only contain identity data attributes that are used for resolving and verifying identities of unknown data records that are external to the reference data system;
receiving, from the reference database, a return message verifying the identity of the first subject and including that includes a first set of combined attributes comprising a selected reference record identifier (ID) identifying a selected reference subject and the first set of query attributes, wherein the selected reference subject is represented by one or more selected reference record attributes and resolves uniquely as a verified first subject based on the first set of query attributes, wherein the selected reference subject is represented by a selected reference data record and is identified by resolving uniquely, by the reference data system, the first subject with the selected reference subject, and wherein the first set of combined attributes represent the verified first subject;
on a condition that the verified first subject resolves uniquely to an identity of a selected private subject using the first set of combined attributes:
linking with certainty the selected private subject with the verified first subject by resolving uniquely the identity of the verified first subject as the selected private subject;
storing, in a private data record of the private data system that includes a private data record ID, one or more attributes contained within the first set of query attributes received from the second enterprise and the selected reference record ID received from the reference database; and
returning, to the second enterprise, the private data record ID to enable the second enterprise to request records pertaining to the selected private subject directly from the first enterprise without further verification the identity of the first subject.
