Professor Hengartner's research interests are in information privacy and in computer and networks security. In particular, he studies security and privacy aspects of emerging mobile and distributed computing systems, such as location-based services, mobile social networking, and electronic voting.
Some sample topics that he has worked on are:
Recently, social-networking applications have started to appear on mobile phones. These applications exploit the phones' positioning capabilities to facilitate interaction between people. From a privacy point of view, this trend is troublesome, because it gives the provider of a social-networking application real-time access to people's location. Prof. Hengartner and his students have designed and implemented privacy-preserving technologies for mobile social networking that do not require the continuous release of people's location to an application provider.
Location-based services provide services to a person based on her location. But what if this person lies about her location to get unauthorized access? Prof. Hengartner and his students have developed technologies that allow people to prove that they are at a location, but without becoming trackable.
End-to-end voter-verifiable voting systems allow voters to verify that their votes were included in the final tally, without revealing which candidate they voted for. Prof. Hengartner and his students have studied and developed several components of such voting systems, such as an efficient auditing mechanism and a publicly auditable way to generate random numbers.
