Abstract

In this paper we show how a simple model that captures user uncertainty can be used to define suitable measures of disclosure risk and data utility. The model generalizes previous results of Duncan and Lambert. We present several examples to illustrate how the new measures can be used to implement existing optimality criteria for the choice of the best form of data release.
