We're setting up a digital independence test instance at #C4DT

https://cloud.c4dt.org

If you have a Switch eduID account, you can test-drive various apps in there. It's a bit slow, so have patience! Also, this is for TEST-DRIVE only, and should not be seen as a reliable instance!

Also let us know if there is a web app you would like to see there. If it's possible, we'll add it.

For our #eID work with @cdengler and Clement Humbert we created a reading list with several presentations of our sources related to #ZeroKnowledgeProofs. You can either look at it on github:

https://eid-privacy.github.io/wp2/2026/04/22/zkp-vault.html

Or download it and open it with Obsidian to browse around. Of course we'd be very happy if you create a PR with your preferred paper on ZKPs!

Reading list for ZKP algorithms and implementations

Are you looking into various Zero Knowledge Proof algorithm and tools? Do you wonder which ones are the most relevant algorithms and implementations? What are the differences between the different approaches? Then you found the right blog entry! This is an introduction to the ZKP Vault page - you’ll find information how to view it locally, and how to add new information under local usage.

Parler de souveraineté numérique en Europe devient de plus en plus courant. Même si ça va prendre beaucoup d'années d'avoir un contre-poids aux grandes entreprises américaines, les solutions émergent et s'organisent. Une fois qu'il y aura de l'argent qui alimente ces solutions alternatives, open source ou pas, l'utilité de ces solutions va augmenter drastiquement.

«L’Europe est le berceau des standards ouverts»: à Paris, la résistance numérique s’organise

Les enjeux de souveraineté numérique étaient au cœur mardi d’un événement parisien auquel a notamment participé le juge de la Cour pénale internationale Nicolas Guillou. Sous sanctions américaines depuis août 2025, il a souligné les effets néfastes de la dépendance technologique européenne

This article highlights a key point: digital transformation requires basic connectivity. With only 38% of the population online, the digital divide in Africa presents significant challenges and opportunities. The competition between space-based solutions and submarine cables is interesting. Despite major infrastructure investments in Africa, China seems to be absent here and worthy of monitoring for geopolitical impact. https://restofworld.org/2026/amazon-starlink-africa/ #WeeklyPick #C4DT #EPFL

Recap of the eID Privacy Hands-on Workshop - C4DT

The Center for Digital Trust hosted a successful workshop on Privacy-Preserving eID last week. We welcomed 14 participants from seven partner organizations including Be-Ys, ELCA, FOITT, Kudelski, SICPA, Swiss Post/SwissSign, and Swisscom. The day-long event combined theoretical foundations with hands-on technical demonstrations. Our focus centered on swiyu, Switzerland’s proposed eID project developed by FOITT, and (...)

Two weights and two measures: if the EU fines Apple and Google over privacy concerns, there is a lot of critizism from the other side of the Atlantic. Now Texas does the same, with even heftier fines, and there seems to be no outcry. Personally I'm all for fining companies who abuse our private data, let's hope that this last fine from Texas encourages the EU to continue their good work in this domain!

Google will pay Texas $1.4B to settle claims the company collected users' data without permission

Google will pay $1.4 billion to Texas to settle claims the company collected data on users without permission. The state’s attorney general announced the settlement Friday. The agreement settles several claims Texas made against the search giant in 2022 related to geolocation, incognito searches and biometric data. The state argued Google was “unlawfully tracking and collecting users’ private data.” Google spokesperson José Castañeda said the agreement settles an array of “old claims,” some of which relate to product policies the company has already changed. Paxton said the $1.4 billion is the largest amount won by any state in a settlement with Google over this type of data-privacy violations.

OK, that took very long, but it finally happened: I have my #C4DT running t-shirt! I think the idea came up first pre-Covid, and constant nagging from my side made it happen!

So if you see me nagging you, don't resist. I'm persistent :)

@neiman @cdengler @ando as far as I know it's working mostly out-of-the box. We had a first semester student project to try to add automatic rooms configured by the LDAP authorizations of the student. But this was more exploratory.

Currently there are at least two instances here at EPFL - the semi-official one, and ours from #C4DT. But C4DT's users will move over to the semi-official one at some point.

Matrix is a widely used open source chat platform. It is an alternative to platforms such as Slack and MSTeams. In line with C4DT’s objective to promote services in the realm of digital trust, we set up our own Matrix instance and migrated our professional communications there in 2019. A privacy-first approach with encrypted chat (...)
