The concept of differential privacy has received considerable attention in the literature recently. In this paper we evaluate the masking mechanism based on Laplace noise addition to satisfy differential privacy. The results of this study indicate that the Laplace based noise addition procedure does not satisfy the requirements of differential privacy.

During recent years the imputation strategy in Statistics Finland has been concretised so that we can speak about an integrated modelling approach (IMAI) to this kind of datacleaning (see Laaksonen 2000&2002a&2003, Chambers et al 2001, Piela and Laaksonen 2001). The strategy has been under consideration and consequently further developed in the two big European Union research projects, that is,...

Statistically defensible methods for disclosure limitation allow data users to make inferences about parameters in a model similar to those that would be possible using the original unreleased data. We present a new perturbation method for protecting confidential attributes in continuous microdata—Random Orthogonal Matrix Masking (ROMM) which preserves the sufficient statistics for multivariate...
