Popis: Data privacy is a very important topic and there are several techniques that aim to provide it. The field of statistical disclosure control is a subset of these techniques and aims to reduce the risk of re-identifying an individual from disseminated data. In particular, the application of Operations Re- search (OR) techniques to the microaggregation problem, which is considered one of the best methods for microdata protection and is known to be NP-hard, has been discussed over various papers. The OR techniques applied to this problem provide an upper bound on the optimal microaggrega- tion and the aim is to improve this bound with new heuristics. Using real data that is typically used in the literature, our computational results show, that dramatic improvements are obtained relative to the literature s most popular heuristics and quite efficiently
