Abstract: A methods, systems, and devices for secure linking and matching of data elements across independent data systems of a first and a second enterprise are disclosed. The system includes a first private data system having a first private database that may include all attributes known to the first enterprise A reference data system having a reference database and is also part of the first enterprise. The reference database may contain a plurality of identity data records that only contain identity attributes that are used for resolving and verifying identities of unknown data records that are external to the reference data system. A first set of query attributes may be used determine whether a subject represented by the first set of query attributes associates uniquely with a subject of any private data record stored in the first private database. A similar comparison may be made in the reference database.

Abstract: A method and system for detecting and queuing data stewardship tasks, the method may comprise receiving, at a private database, incoming identity information comprising one or more received data record attributes; comparing the one or more received data record attributes to a plurality of saved data records in the private database. Each saved private data record may include one or more saved attributes. A data stewardship task record is created that contains the received data record attributes and saved data record attributes that are near matches to the received data record. The data stewardship task is displayed to indicate a match quality for each of the received data record attributes and the saved data record attributes. The match quality may be indicated using a color coding scheme that uses a unique color or lack of color to indicate one of a match, a partial match, and no match.
