R. D. Chintamani, I. F. Shaikh, A. D. Waghmare . Hiding Sensitive Association Rules on Stars. Emerging Trends in Computer Science and Information Technology (ETCSIT2012). ETCSIT, 1 (April 2012), 16-19.
Current technology for association rules hiding mostly applies to data stored in a single transaction table. This work presents a novel algorithm for hiding sensitive association rules in data warehouses. A data warehouse is typically made up of multiple dimension tables and a fact table as in a star schema. Based on the strategies of reducing the confidence of sensitive association rule and without constructing the whole joined table, the proposed algorithm can effectively hide multi-relational association rules. Examples and analyses are given to demonstrate the efficacy of the approach.
