  • Systems and methods to relate multiple unit level datasets without retention of unit identifiable information
    Publication number: 20060085454
    Abstract: A method by which researchers may receive unit level data (individual person records) from multiple sources and aggregate that data without receiving personally identifiable data. Since the unconstrained aggregation of seemingly non-identifying data elements can eventually lead to subject identification, the aggregation is limited to a predefined data aggregation domain.
