Wouter Lueks (post-doctoral researcher at EPFL) will present "CrowdNotifier: Decentralized Privacy-Preserving Presence Tracing" on November 3rd at 12:30.
There is growing evidence that SARS-CoV-2 can be transmitted beyond close proximity contacts, in particular in closed and crowded environments with insufficient ventilation. To help mitigation efforts, contact tracers need a way to notify those who were present in such environments at the same time as infected individuals. Neither traditional human-based contact tracing powered by handwritten or electronic lists, nor Bluetooth-enabled proximity tracing can handle this problem efficiently. In this talk, I introduce CrowdNotifier, a protocol that can complement manual contact tracing by efficiently notifying visitors of venues and events with SARS-CoV-2-positive attendees. We prove that CrowdNotifier provides strong privacy and abuse-resistance, and show that it can scale to handle notification at a national scale.

Our paper “Inexpensive Brainwave Authentication: New Techniques and Insights on User Acceptance” has been accepted for presentation at the 30th USENIX Security Symposium. In this research, we explore and evaluate different brain biometric techniques to authenticate users with consumer BCI tools and investigate user perceptions towards accepting such technologies. Our results show that it is feasible to recognize users based on brain responses to images. With regard to adoption, users call for simpler devices, faster authentication, and better privacy.
Thorsten Strufe is a discussion guest at the 'Bonner Tage der Demokratie' (engl. Bonn Days of Democracy).
On May 4, starting at 7 p.m., he will speak in the opening panel about fundamental rights in relation to social media.

Our article "Browsing Unicity: On the Limits of Anonymizing Web Tracking Data" (Clemens Deusser, Steffen Passmann and Thorsten Strufe) has been accepted for presentation at the IEEE S&P ("Oakland")! In the paper we examine the "anonymizing methods" commonly used by industry and show that they are largely ineffective even when applied to an extent that essentially destroys all utility of web tracking data. Using the example of a data set of a large European audience measurement provider, we show that the claim that "coarsening" leads to de-identified data sets is nonsense, since even in extreme cases anonymity is not achieved. Clemens Deusser will present the article at the IEEE S&P in May 2020, congratulations Clemens and Steffen!
Our article "Breaking and (Partially) Fixing Provably Secure Onion Routing" (Christiane Kuhn, Martin Beck and Thorsten Strufe) has been accepted for presentation at IEEE S&P ("Oakland")! In the paper we identify a vulnerability in a lightweight anonymization system ("HORNET") which was previously considered to be proven secure. We then find a vulnerability in the underlying packet format SPHINX, which is also used for other anonymization services. Finally, we find that the evidence framework of Camenish and Lysyanskaya used in both cases is flawed and fix the found bugs to share. Christiane Kuhn presents the article at the IEEE S&P in May 2020. Congrats, Christiane and Martin!
