ISRI Seminar Series Presents: Christopher W. Clifton, Assoc. Professor Purdue University Title: Privacy Conflicts Inherent in Data Analysis Wean Hall 4625 Wednesday, March 29th 10:30-11:30am Abstract: Privacy-Preserving Data Mining has generated many research successes, but as yet little real-world impact. One problem is that we do not yet have accepted definitions of privacy; either legal, social, or technical; that apply to privacy-preserving data mining. This talk discusses this issue, with a brief overview of what we can do and a survey of work that can help with what needs to be done. In spite of this problem, there are real-world scenarios that can be addressed by today's technology; the talk concludes with a discussion of such areas and the research needed to make technology transfer happen. Bio: Dr. Clifton works on challenges posed by novel uses of data mining technology, including privacy-preserving data mining, data mining of text, and data mining techniques applied to interoperation of heterogeneous information sources. Fundamental data mining challenges posed by these applications include extracting knowledge from noisy data, identifying knowledge in highly skewed data (few examples of "interesting" behavior), and limits on learning. He also works on database support for widely distributed and autonomously controlled information, particularly information administration issues such as supporting fine-grained access control. Prior to joining Purdue, Dr. Clifton was a principal scientist in the Information Technology Division at the MITRE Corporation. Before joining MITRE in 1995, he was an assistant professor of computer science at Northwestern University.
