Abstract

In this chapter we consider the application of some perturbative techniques to produce safe microdata. As discussed in Chapter 2, the risk of disclosure is conceived of as arising from the possibility that an intruder matches the values of key variables in the microdata to corresponding values in prior information. The approach in this chapter is to perturb the values of potential key variables in the microdata so that they cannot be matched to external data sources so easily.
