On Enhancing Utility in A-anonymization
k-anonymity is one of the most well studied models of privacy preservation technology. k-anonymity protects the identification of an individuals record from at least (k-1) other records. In this paper, we propose a new quality metric, called the utility-privacy (UP) metric, which overcomes the limitations of existing one dimensional metrics, representing either privacy measure or data utility measure, used in privacy preserving data sharing. The proposed UP metric represents both the privacy measure and utility measure of the anonymous data. We then present a new heuristic algorithm that achieves k-anonymity with high utility and utility-privacy measure. Comparisons of experimental results of our algorithm with those of four other well-known algorithms for k-anonymity show that our algorithm performs the best both in utility measure and utility-privacy measure.
