ols that will help organ- izations mine data while preserving privacy. "There is a tension between individuals' privacy rights and the need for, say, law enforcement to process sensitive information," says principal investigator Dan Boneh, an associate professor of computer science and electrical engineering at Stanford Univer- sity. For example, a law enforcement agent might want to search several airline databases to find individuals who satisfy certain criteria. "How do we search these databases while preserving privacy of people who do not match the criteria?" asks Boneh, who notes that similar questions apply to health and financial databases. Government and business both want more access to data, notes Joan Feigenbaum, a Yale computer science professor and one of the project's inves- tigators. She notes that individuals want the advantages that can result from data collection and analysis but not the disadvantages. "Use of transaction data and surveillance data need to be consistent with basic U.S. constitutional struc- ture and with basic social and business norms," she says. The project will join technologists, lawyers, policy advocates, and domain experts to explore ways of meeting potentially conflicting goals-respecting individual rights and allowing organizations to collect and mine massive data sets. They will participate in biannual workshops and professional meetings, collaborate on publications, and jointly advise student and postdoctoral researchers. The researchers hope, for example, to develop tools for managing sensitive data in peer-to-peer (P2P) networks. Such networks allow hundreds, or even millions, of users to share data, music, images, movies, and even academic papers without the use of a centralized Web server. But participants' com- puters also may hold private files that users may not want to share. THE SEEING EYE Additionally, the researchers will explore ways to enforce database policies. For example, privacy-preserving policies need to be better integrated into database management
