Privacy concerns could make many potential users hesitant to use the Bluetooth-based app to contain the pandemic, as outlined by the developers. The President of the German Gesellschaft für Informatik Prof. Dr. Hannes Federrath, who is a member of the research project, considers the app harmless under certain conditions. He announced this in the fact check for “maischberger. die woche” broadcast on 01.04.2020:
“Bluetooth technology, as it is to be used in the case of the targeted Corona app, has the advantage over the use of, for example, location data from mobile radio that the distances to other smartphones in the vicinity can be measured very precisely and are only stored locally in the mobile phone. No movement profiles are created by the user and all data is stored under constantly changing identifiers. The main purpose of this app is to determine whether someone has been at a distance of less than two meters from an infected person for a long time. The identity of the user is not necessary for the notification at all and should therefore not be stored anywhere. If the data is transmitted in encrypted form and stored for a limited period of time – 21 days – there is no reason why this application should not be used from the point of view of data protection law and IT security.”
The Hamburg Interdisciplinary Summer School “Governance Technologies: Privacy, Fairness & Transparency” was a terrific event. Held at the guest house of the Universität Hamburg and the adjacent Leibniz Institute for Media Research/Hans-Bredow-Institute, scientists from ten countries came together to discuss manifold ideas. Algorithmic accountability, information privacy, and european communication rights are only a few examples for the manifold topics discussed. The varying interdisciplinary backgrounds of all researchers mutually enriched one another. Furthermore, the presentations of our keynote-speakers – “The Online Tragedies and How to Resolve Them” by Nikolas Guggenberger, “Digital identities from a European perspective” by Bart Jacobs, “Law and Computer Science: Competing Legislators?” by Mireille Hildebrandt, and “Contesting Algorithms” by Niva Elkin-Koren – provided many opportunities for discourses. The panel discussions on domain-specific views on privacy, fairness, and transparency as well as the approaches of how to make interdisciplinary research work in the context of law, ethics & computer science were very insightful. Moreover, the visit to the panel discussion of the ThIS! event regarding responsible experimentation with AI: what to dare, how to care in OTTO’s executive lounge completed the variety of the summer school.
