Abstract

This chapter introduces a formal study on access-unrestricted data anonymity. It includes four aspects: (1) it analyzes the impacts of anonymity on data usability; (2) it quantitatively measures privacy disclosure risks in practical environment; (3) it discusses the potential factors leading to privacy disclosure; and (4) it proposes the improved anonymity solutions within typical k-anonymity models, which can effectively prevent privacy disclosure that is related with the published data properties, anonymity principles, and anonymization rules. The experiments have found these potential privacy inference violations and shown the enhanced privacy-preserving effect of the new anti-inference policies to access-unrestricted data publication.
