The certificate linked to the virus will not be available before June in Switzerland. Until then, here are twelve answers linked to questions of security, data and accessibility concerning what some call the “Immunity Passport”. In particular, Jean-Pierre Hubaux, C4DT Academic Director, provides insights on the questions linked to data.
French-language news paper ‘Le Temps’ published an opinion piece by C4DT’s Academic Director and Head of the LDS lab at EPFL, Jean-Pierre Hubaux, on trusting the SwissCovid app. Prof. Hubaux raises the point that the excessive focus on privacy protection has cast doubt on a tool which makes it possible to defend other rights.

Increasingly, reports warn that state-sponsored actors use social media to spread fake news/disinformation in order to sow distrust and create panic during pandemics and create discord and polarized opinions among people on political issues during democratic elections. Adding to this, social media platforms’ algorithms “add salt to the wound” by feeding their users posts which are aligned with their opinion in order to increase their screen time. How serious and how massive is the problem? What are its implications? And what can/should be done about it?
During this forum, organized jointly by the Center for Digital Trust (C4DT), the CyberPeace Institute and the Graduate Institute’s Centre for Trade and Economic Integration (CTEI) in Geneva, we will discuss not only the technological aspects of this phenomena, but also the regulatory role executive and legislative branches of governments should play. Societal, economical and geopolitical implications will also be debated. This event is open to the general public.

Click is the prominent way that users interact with web applications. Attackers aim to intercept genuine user clicks to either send malicious commands to another application on behalf of the user or fabricate realistic ad click traffic. In this talk, Prof. Wei Meng investigates the click interception practices on the Web.

Voilà qui est intéressant, mais guère surprenant : lorsque l’on s’appuie sur les intelligences artificielles, on perd peu à peu l’habitude de ce que l’on savait faire par soi-même. C’est probablement analogue au fait de ne plus être capable de marcher de longues distances quand on prend constamment la voiture ou le train. J’aurais bien (…)
This piece is interesting for managers because it reframes sovereignty as a company-level operating challenge rather than a geopolitical abstraction. Instead of blacklisting vendors, a reactive and politically driven mistake, organizations must consider which services are critical and how to maintain them. Geopolitics has entered the boardroom, and the technical scope now explicitly encompasses cloud (…)
The Center for Digital Trust (C4DT) hosted the hands‑on workshop “LLM Benchmarking” on May 19th 2026. Thirteen attendees from a wide range of our partners, ELCA, Kudelski, SICPA and Swisscom, gathered to learn how to use benchmarks to choose the best LLM model for their use cases. The day‑long event started off with a lecture on (…)
To promote research and education in cyber-defence, the EPFL and the Cyber-Defence Campus have jointly launched the “CYD Fellowships – A Talent Program for Cyber-Defence Research. ”The 14th call for applications is now open with a deadline of 19 August 2026 for Doctoral and Distinguished Postdoctoral Fellowship applications.
A slightly morbid example of how you never know what your data might eventually be used for. Although this is not exactly a classical case of your privacy being violated, I have some doubts that everyone who enthusiastically chased cute virtual monsters in their neighborhood would also have volunteered to collect data to train military (…)
We use Matrix, too, so this issue hits close to home for us. The timing is infortunate. Europe is actively working to reduce its digital dependency, and this incident has landed right in the middle of those efforts, ready to be weaponized by skeptics. However, the details matter. From what is currently known, neither the (…)
Amongst all the big news, I really like blog posts like this – just a cryptographer finding an interesting oddity, deciding to dig into it, and sharing their findings with the rest of us, even if nothing big came of it.
A reality check for anyone assuming AI subscriptions will stay at today’s prices — or get cheaper. Repricing is only a matter of time. But beyond the economics lies a sovereignty trap: cheap access accelerates dependency, erodes internal capability, and eliminates negotiating leverage before the real cost arrives. By then, workflows and data are already (…)
I find this interesting because it extends the debate about digital sovereignty beyond software and hardware to the scarce resource of satellite communication spectrum. The EU’s 20-year strategy clearly demonstrates its vision for autonomous, secure infrastructure, such as the IRIS² project. I hope this assertive yet justified strategy progresses without provoking retaliation from the US (…)
This piece offers an optimistic path forward for AI governance. Rather than searching for consensus on abstract ethical principles, we can build on the public values that our societies have already agreed upon. The author also makes the important point that experimentation in AI governance will inevitably produce failures and that this is not only (…)
As the global AI landscape consolidates around US and Chinese dominance, every nation outside this duopoly faces an urgent question: how can countries retain meaningful control over a technology increasingly expected to shape their economic competitiveness, national security, and societal resilience? From the viability of sovereign cloud architectures and open-weight foundation models to the governance mechanisms needed to ensure AI systems reflect Swiss values and legal frameworks, this conference brings together industry leaders, researchers, legal experts, policymakers, and civil society actors to assess the concrete levers of AI sovereignty and work toward actionable recommendations for a Swiss sovereign AI strategy.
Now even the pope chimes in on giving his ideas how to use LLMs in a responsible way. His name predecessor, Leo the XIII, had many things to say about responsible capitalism. Now is the time to set the agenda straight with regards to LLMs: the pope puts the human in the center again, asks (…)
It’s encouraging to see digital sovereignty discussions beginning to bear fruit, though much of that fruit is still unripe. The more closely the non-US community examines the issue, the more complex it becomes: ‘sovereign’ cloud computing means little if the underlying hardware is produced in the US or China. A server is not just one (…)
November 10th, 2026, 09h30-18h30, Starling Hotel, 1025 Saint-Sulpice Introduction The global AI landscape is consolidating around two dominant poles. Global corporate AI investment reached $581.7 billion in 2025 — up 130% year-over-year — while generative AI investment alone surged nearly fivefold to $170.9 billion, with the overwhelming share of this capital concentrated in the United (…)
