.... query sets, detecting inferences by auditing all queries asked by a specific user [12, 10, 26, 6] suppressing sensitive data in released statistical tables [13] grouping tuples and treating each group as a single tuple [11, 32] Perturbation based techniques add noise to source data or outputs [35, 5, 34]. Other aspects of inference problem include the inference caused by arithmetic constraints [8, 7] inferring approximate values instead of exact values [30] and inferring intervals enclosing exact values [28, 27, 29] The inference control methods proposed for statistical databases do not ....

....enough to the unperturbed ones, leading to interval based inference. Random data perturbation (RDP) methods (i.e. adding random noise to senserive data) have been studied for many years, especially in the statistical database literature, to prevent both exact inference and statistical inference [12, 1, 11, 7, 10, 8]. For numerical attributes, most RDP methods generate noise based on Gaussian distribution [7, 10, 8] Such method is not effective to prevent interval based inference since arbitrarily small noise could be generated. To illustrate this, assume that a random noise from Gaussian distribution with ....
....inference, whereas this probability is zero for the RDP based on e Gaussian distribution. Discussion Formula (5) indicates that the error estimate to the query response is in a statistical sense. If database users are not satisfied with this, a correction scheme is to be developed. Traub et al. [11] proposed the following remedy scheme: i) monitor the error in each query and check whether it exceeds a predetermined threshold; ii) if the error threshold is exceeded and if the query size is large enough, simply perturbs the query response by adding some random noise until the error of the ....
