Abstract
Systems and methods are provided for selectively determining privacy guarantees. For example, a first class of data may be guaranteed a first level of privacy, while other data classes are only guaranteed some lesser level of privacy. An amount of privacy is guaranteed by adding noise values to database query outputs. Noise distributions can be tailored to be appropriate for the particular data in a given database by calculating a 'diameter' of the data. When the distribution is based on the diameter of a first class of data, and the diameter measurement does not account for additional data in the database, the result is that query outputs leak information about the additional data.
