Abstract
A database has a plurality of entries and a plurality of attributes common to each entry, where each entry corresponds to an individual. A query q is received from a querying entity query q and is passed to the database, and an answer a is received in response. An amount of noise e is generated and added to the answer a to result in an obscured answer o, and the obscured answer o is returned to the querying entity. Thus, a level of protection of privacy is provided to each individual represented within the database.
