Abstract: Reductions to bandwidth storage resource use needed to safely and securely provide longitudinal data related to individuals to authorized parties from disparate sources are realized by employing the present disclosure. As the data related to the individual are held by various originating and aggregating databases in a variety of formats, with each database having different sharing policies, and the user similarly specifying different access permissions to personal data, a hub that manages access in a hybrid distributed/aggregated mode enables requestors to review data at a single point of access in accordance with specified access permissions from the databases or the individual. Reduced weight records, using permitted data fields, are aggregated and links to the records are provided according to the determined permission levels.

Abstract: Expanded data processing for entity matching is provided. A request for determining a matching entity is received. The received request is parsed to determine demographic field data associated with the request. A first look up operation is performed in an indexed demographic data for a first demographic field associated with the request. A first list of entities matching with the first demographic field data is received in response to the first look up operation. A second look up operation is performed in the indexed demographic data to determine a set of demographic attributes associated with each entity on the first list. The demographic attributes correspond to a second demographic field associated with the request. A matching confidence for whether the entity is associated with a given entity in the first list is determined based on a comparison between the demographic field data and the demographic attributes.
