Microdata protection in statistical databases has recently become a major societal concern and has been intensively studied in recent years. Statistical Disclosure Control (SDC) is often applied to statistical databases before they are released for public use. Microaggregation for SDC is a family of methods to protect microdata from individual
identification. SDC seeks to protect microdata in such a
way that can be published and mined without providing any
private information that can be linked to specific individuals.
Microaggregation works by partitioning the microdata into
groups of at least k records and then replacing the records
in each group with the centroid of the group. This paper
presents a clustering-based microaggregation method to
minimize the information loss. The proposed technique
adopts to group similar records together in a systematic
way and then anonymized with the centroid of each group
individually. The structure of systematic clustering problem
is defined and investigated and an algorithm of the proposed
problem is developed. Experimental results show that our
method attains a reasonable dominance with respect to both
information loss and execution time than the most popular
heuristic algorithm called Maximum Distance to Average
Vector (MDAV).
