....et al. the average over each group instead of individual records. A similar idea has also been discussed in statistical database literature where a database is partitioned into atomic populations (i.e. mutually exclusive groups) that constitute the raw materials available to the database users [3, 2, 13, 17]. Previous microaggregation methods require that the size of each partition group be a fixed constant k, called fixed size microaggregation [5, 4] Recent developments [6, 9] have concentrated on reducing information loss by allowing the size of each partition group to vary (with lower bound k) ....

The perturbation family includes swapping values between records [12] replacing the original database by a sample from the same distribution [33] 42] adding noise to the values in the database [52] 57] adding noise to the results of a query [4] and sampling the result of a query [11] ....
