Abstract: Systems, methods, and manufactures for enhancing the determination of differential privacy query results. A computer implemented method for enhancing the determination of differential privacy query results is provided. The computer implemented method includes obtaining a first query of a database, determining a query result by executing the first query on the database, determining a noisy result by adding noise to the query result, wherein the noise is determined based on a first statistical evaluation of the first query, determining a first hash value identifying the first query based on one or more of the first statistical evaluation and a second statistical evaluation of the first query, maintaining the noisy result linked to the first hash value in a result cache, and returning the noisy result from the result cache in response to a subsequent query when a second hash value identifying the subsequent query is determined to be statistically similar to the first hash value.

Abstract: Systems, methods, and manufactures for enhancing the determination of differential privacy query results. Implementations may include a database; a result cache; a processor; and a media storing instructions that, when executed by the processor, cause the system to perform operations that include obtaining a query of the database; determining that a specificity of the query exceeds a specificity threshold; determining that the result cache lacks any query results of previous queries that are substantially equivalent to the query; partitioning the database into a plurality of groups; determining a query result by executing the query on the plurality of groups; determining a sensitivity of the query and a nominal measurement of the query; determining a noisy result by adding noise to the query result based on the sensitivity and the nominal measurement; storing the noisy result in the result cache; and providing the noisy result in response to the query.
