Research Overview
My group researches privacy issues related to anonymized analytics. A long-standing problem is that of providing statistical or aggregate data about users without leaking information about individual users. Past strongly-anonymous systems, like K-anonymity and Differential Privacy, provide poor utility. As a result, most so-called “anonymous” analtyics is done over weakly anonymized data. We are working a designing and building a system that provides strong anonymity, high utility, and easy configuration. The project page is at: http://anon-analytics.mpi-sws.org/ .
