Privacy in Statistical Databases

The paper introduces into the methodology for disclosure limitation offered by the software package τ-ARGUS. Those methods have been applied to the data sets of a library of close-to-real-life test instances. The paper presents results of the tests, comparing the performance of the methods with respect to key issues such as practical applicability, information loss, and disclosure risk. Based on these results, the paper points out which of the alternative methods offered by the package is likely to perform best in a given situation.
