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.
