Abstract
The field of Statistical Disclosure Control aims at reducing the risk of re-identification of an individualwhen disseminating data, and it is one of the main concerns of national statistical agencies. OperationsResearch (OR) techniques were widely used in the past for the protection of tabular data, but not formicrodata (i.e., files of individuals and attributes). This work presents (as far as we know, for the firsttime) an application of OR techniques for the microaggregation problem, which ...
