There exists an enormous amount of useful information gathered by statistical agencies. However, the privacy issues of involved entities limit them for public usages. Different computational privacy models are suggested to protect the privacy of individuals during data publishing such as ?-anonymity. In a ?-anonymous dataset, each combination of identifying attributes occurs in at least ? records. Microaggregation is a successful mechanism to realize ?-anonymity. However, it is proved to be NP-hard in general. This paper addressed the problem of multivariate microaggregation and introduces a compact encoding to solve it using an evolutionary approach. Experimental results confirm the superiority of the proposed method in 88% of test cases in compare with similar studies in the literature.
