Invited Talk - Inference Control Problems in Statistical Database Query Systems
Lawrence H. Cox · Kluwer Academic Publishers eBooks · 2006
The advent of public use statistical database query systems raises problems of controlling inference of confidential information. Some of these problems are new while others present new challenges in terms of scalability of computational algorithms. We examine three problems: obtaining exact interval estimates of data withheld to address confidentiality concerns; confidentiality issues associated with the release of ordinary least squares regression models; and, confidentiality issues associated with the release of spatial statistical models based on ordinary kriging. For the first, we treat the database as one large multi-dimensional contingency table (large number of records, large dimension). These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
