Abstract: A computer system contains a module configured to receive a query, to request rows and columns from a data store, to add or remove rows in such a way that combinations of queries cannot be used to infer information about individuals in the data store. The module executes a statistical computation over the adjusted rows and columns to produce a perturbed answer so that neither the perturbed answer alone, nor repeats of the perturbed answer can be used to infer information about individuals in the data store.

Abstract: An anonymizing method for a database system is provided. The method includes receiving a query, identifying one or more attack components in the query, computing one or more noise elements from the one or more attack components, and computing fixed noise or fixed thresholds from the one or more noise elements.

Abstract: A computer system includes a database configured to receive a query and to produce a list of User IDs and an anonymization module. The anonymization module is configured to receive a list of user IDs in response to a query, the list of user IDs defining a true user count, generate a noisy user count of the list of user IDs, compare the true user count to a first threshold value stored in memory, compare the noisy user count to a second threshold value stored in memory, and output the noisy user count only if the true user count is greater than the first threshold value and the noisy user count is greater then the second threshold.
