Cynthia Dwork develops theoretical foundations for privacy-preserving data analysis. With Aaron Roth, she coauthored The Algorithmic Foundations of Differential Privacy by Cynthia Dwork and Aaron Roth. For neighboring datasets differing in one individual's contribution, pure -differential privacy requires, for every output event ,The quantifier over events protects against more than a few preselected attacks.[ref]
For example, releasing an exact count can disclose participation when it changes from zero to one. A randomized mechanism trades some accuracy for a bound on how distinguishable those two situations become. Dwork's research account places this work within the use of theoretical computer science to formalize societal problems.[ref]
