Statistical Disclosure Limitation with Released Marginals and Conditionals for Contingency Tables
Aleksandra Slavković · 2004
The goal of statistical disclosure limitation is to develop methods and tools that while preserving confidentiality can provide access to useful statistical data, not just a few numbers. In this paper we consider releases from contingency tables in the form of marginal counts and observed conditional frequencies. We link data utility to log-linear models, and evaluation of disclosure risk to bounds on cell entries in the table. We illustrate some of the selected ideas from [8, 18, 17, 12] with 2^4 example.
