Abstract

One non-limiting, exemplary method includes: receiving a query on a structured data set; transforming the query into a plurality of set membership queries on a plurality of sets, wherein the plurality of sets are obtained by modifying the structured data set; determining a plurality of first answers corresponding to the plurality of set membership queries; processing the plurality of first answers to obtain a second answer corresponding to the query; and returning the second answer. This exemplary method can be extended, for example, to a three-party system involving a data source, a responder and a query source.
