چکیده

In recent years Statistics Netherlands has developed a prototype version of a software package, ARGUS, to protect microdata files against statistical disclosure. In 1995 the present prototype version of ARGUS, namely version 1.1, has been released. In this paper both the rules, based on checking low-dimensional combinations of values of so-called identifying variables, and the techniques, global recoding and local suppression, applied by Statistics Netherlands to protect microdata sets are described. Subsequently, it is examined how ARGUS incorporates these ideas. Firstly, the data needed by ARGUS are described. Secondly, it is explained how disclosure control measures can be taken by means of ARGUS. Thirdly, the information generated by ARGUS to determine the global recodings is described. Based on this information the user of ARGUS can decide how the variables should be recoded.
