چکیده
Many statistical agencies nowadays operate or envision tools for ad hoc creation and visualization of aggregate tables, ideally with web-access facilities. Users should be able to easily create their own customized tables. However, especially with heavily skewed business data, disclosure control issues usually are a big obstacle in this context, hardly solvable by traditional methods like cell suppression. For population counts data the Australian Bureau of Statistics has implemented a SDL method based on post-tabular noise addition. The US Census Bureau on the other hand has developed a method based on pre-tabular multiplicative noise to protect enterprise tabular data. This paper proposes a new method based on an idea for post-tabular stochastic noise. The method proved to give encouraging results when tested on tabulations of German business tax statistics.

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.

The European Union is facing the problem of releasing microdata in a multinational setting i.e. microdata stemming from twenty seven member states. Different laws, methodologies, practices and cultural approaches to confidentiality may severely limit the possibility of obtaining comprehensive anonymised data sets. We recall the approach adopted in Europe to design and manage harmonised statisti...

Theoretical methods and software are available for performing optimal complementary cell suppression (CCS) in tables. The released resulting suppression patterns comprise algebraic circuits which define alternative tables for the original table while controlling variation between original and alternative cell values. For an important class of statistical tables including two-way tables, these c...
