Privacy Preserving Data Mining

Chris Clifton and Jaideep Vaidya - Department of Computer Science, Purdue University

Feb 27, 2002

Abstract

Data mining technology has emerged as a means of identifying patterns and trends from large quantities of data. Data mining and data warehousing go hand-in-hand: most tools operate by gathering all data into a central site, then running an algorithm against that data. Privacy considerations can prevent or limit sharing between sites, preventing us from creating a data warehouse. In this talk, we discuss this problem, and present solutions that enable us to obtain global data mining results without compromising local privacy. In particular, we will look at the problem of mining globally correct association rules without sharing local information.
