Disclosure risk for microdata stemming from official statistics

Abstract

"In the research project on data anonymity, the possibilities and difficulties of restoring the identity of respondents, whose data have been anonymized, were tested in realistic simulations. In this paper the results of an application of a) a matching procedure and of b) a method based on discriminant analysis are reported. In the experiments carried out, empirical data of a handbook about German scientists and scholars and the German microcensus were used. A check of the results by an independent data-trustee demonstrated that a real intruder has more difficulties achieving an identification than is frequently assumed."
