Abstract: A hardware database privacy device is communicatively coupled to a private database system. The hardware database privacy device receives a request from a client device to perform a query of the private database system and identifies a level of differential privacy corresponding to the request. The identified level of differential privacy includes privacy parameters (?,?) indicating the degree of information released about the private database system. The hardware database privacy device identifies a set of operations to be performed on the set of data that corresponds to the requested query. After the set of data is accessed, the set of operations is modified based on the identified level of differential privacy such that a performance of the modified set of operations produces a result set that is (?,?)-differentially private.

Abstract: Techniques are described for responding to queries of a private database system. A request is received from a client device to perform a query of the private database system. A level of differential privacy corresponding to the request is identified comprising privacy parameters ? and ?. A set of data stored in the private database system and a set of operations corresponding to the query are identified. The set of operations comprises generating a density plot visualization for one or more subsets of the set of data. The set of data is segmented into disjoint regions. For each disjoint region, a density is identified, and the density is plotted in a differentially private density plot visualization using one or more graphical elements.
