TL;DR: An overview of the new and rapidly emerging research area of privacy preserving data mining is provided, and a classification hierarchy that sets the basis for analyzing the work which has been performed in this context is proposed.
Journal ArticleDOI
Association rule hiding
TL;DR: This work investigates confidentiality issues of a broad category of rules, the association rules, and presents three strategies and five algorithms for hiding a group of associationrules, which is characterized as sensitive.
Proceedings ArticleDOI
Disclosure limitation of sensitive rules
TL;DR: This paper attempted to selectively hide some frequent itemsets from large databases with as little as possible impact on other non-sensitive frequent itemets.
Journal ArticleDOI
Using unknowns to prevent discovery of association rules
TL;DR: This work introduces a method for selectively removing individual values from a database to prevent the discovery of a set of rules, while preserving the data for other applications.
