Title: Synthetic Data: We Made the Numbers Up, but It's OK to Use Them

Abstract: Synthetic data, the practice of releasing scientific data that are subject to privacy and confidentiality protections by sampling from the joint posterior predictive distribution of the confidential data, is gaining traction in the official statistical community. Visit http://lehdmap.dsd.census.gov/ to see the U.S. Census Bureau's first official synthetic data product, which I helped to design. There is a fundamental tension between the extent of confidentiality protection and the analytic usefulness of the released data. Economists model this tradeoff by using a production possibility frontier for the two "goods"--privacy protection and information content. (Statisticians call this the risk-utility tradeoff, but I'll explain why I prefer to reserve "utility" to describe the data user's preferences and not the data provider's technology.) I've got lots of examples, but you should feel free to suggest some of your own problems. If you want more background, visit INFO 747 at http://www.vrdc.cornell.edu/info747/.
