DLAW03 - New Developments in Data Privacy

We try to compare different practical perturbation schemes for frequency tables used by certain agencies, with different parameters, using the parameters of Differential Privacy guaranteed by these schemes. At the same time we look at utility of perturbed data in terms of loss functions that are common in statistics, and also by trying to study the conditions required for certain statistical properties of the original table, such as independence of certain variables, to be preserved under the perturbation. The `worst case' nature of Differential Privacy appears problematic, and so are alternative definitions, which rely on scenarios that are not the worst.  This is ongoing work, and we still have many unanswered questions which I will raise in the talk in hope for help from the audience.
