My group researches privacy issues related to practical data anonymization. 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. In research partnership with Aircloak GmbH, we have developed Diffix, a practical data anonymization mechanism that provides strong anonymity, high utility, and easy configuration. Diffix is now being developed in the Open Diffix Project.
