Abstract: Disclosure risk occurs when there is a high probability that an intruder can identify an individual in released sample microdata and confidential information may be revealed. A probabilistic modelling framework based on the Poisson log-linear model is demonstrated for quantifying disclosure risk in terms of population uniqueness when population counts are unknown. This method does not account for measurement error arising either naturally from survey processes or purposely introduced as a perturbative disclosure limitation technique. The probabilistic modelling framework for assessing disclosure risk is expanded to take into account the misclassification/ perturbation and demonstrated on sample microdata which has undergone a perturbation procedure. Finally, we adapt the probabilistic modelling framework to assess the disclosure risk of non-random samples from sub-populations and show some initial results.

This is joint work with Prof. Chris Skinner of the London School of Economics and Political Science.

Natalie Shlomo is Professor of Social Statistics at the University of Manchester and currently an organiser of the programme Data Linkage and Anonymisation at the Isaac Newton Institute of Mathematical Sciences. Her research interests are in survey methodology and official statistics. She is the UK principle investigator for several collaborative grants from the 7th Framework Programme of the European Union all involving research in improving survey methods and dissemination. She is an elected member of the International Statistical Institute and a fellow of the Royal Statistical Society.

All welcome! Refreshments will be served before the talk.

There are two spare tickets for dinner with the speaker after the event. If you would like to come to hall at Trinity with Prof Shlomo, please RSVP to Khyla (kk538) by 3pm Saturday.
