Disclosure risk assessment in perturbative microdata protection

Abstract

This paper describes methods for data perturbation that include rank swapping and additive noise. It also describes enhanced methods of re-identification using probabilistic record linkage. The empirical comparisons use variants of the framework for measuring information loss and re-identification risk that were introduced by Domingo-Ferrer and Mateo-Sanz. © 2002 Springer-Verlag Berlin Heidelberg.
