We are lucky to be visited by @gianlucastringhini.com who gave an insightful talk about research on online safety as part of our @kastel-labs.bsky.social distinguished lecture series: dls.kastel.kit.edu today -
Thanks a lot!

Very unusual but probably the best conference keynote we ever had the pleasure of attending: David Basin explaining how security and privacy by design may actually work with the help of formal logic.

🎉 Happy to share that Julian presents our paper showing how beamforming feedback information - openly broadcast by WiFi devices and accessible to any passive network sniffer - can identify individuals with near-perfect accuracy, even those who don't carry any devices, at ACM CCS in Taipei this week!

Can't be correct, is it!?

From gait and gaze to WiFi signals and XR avatars-our bodies reveal far more than we think. I shared empirical results showing how easy it is to re-identify individuals in so-called “anonymized” datasets, even when advanced techniques like federated learning or differential privacy are applied.

I had the pleasure of giving a keynote APVP '25 in Poitiers yesterday on a topic that’s becoming increasingly urgent: the (non-existing) privacy of behavioral biometrics.

One of our @kastel-labs.bsky.social projects explained: How smart city sensors infringe on your privacy, featuring our Julian, Patricia (and Felix behind the scenes), as well as your's truly as a train wreck (after a 4h sleep night due to having been on a train wreck the night before 😅)

Haha! "It's scientifically correct if it supports my political point of view!!1!1"
We used to look up to the US, but now we're rather happy to not also live through another period of the dark ages..

Back from CPDP and our stellar panel on Privacy Threats of Medical Data, with Franziska Boehm, Dominique Schroeder, Kim Wuyts, and Isabel Wagner.
I've learned a lot from the panels and I'm grateful for the invitation from the organizers of the CS Track, Marit Hansen and @xotoxot.bsky.social!

Campus day 2025 at #KITKarlsruhe, and our expositions of Matin and Julian have attracted lots of interest and raised controversial discussions. Needless to say that we had a blast! 🎉

Frightening the hell out of 90% of science globally in one simple step (I hope the orange clown won't learn about this, or we'll have to host our own ShareLatex, again =-o)

Radar, used e.g. in vehicles, is claimed to "preserve privacy". In her thesis Cinthya investigated this claim during her ERASMUS stay with us.
Turns out several attributes (age, sex, etc) can be reliably inferred. Congrats and thanks for the great work!

I participated in the Wings for Life World Run, and it actually went better than I had anticipated :)
It's Red Bull advertisement, but all donations go to spinal cord research, so I guess it's ok :)

Fresh off the press: Simon's survey on different attempts to anonymize behavioural biometric data has been accepted at ACM Computing Surveys!
💪 Excellent work, congrats! 💪
It's gold open access, you can find it here:

Worry less, do more - we're well situated in Europe, the digital transformation is far from over and markets are still young is probably the shortest possible summary of Michael's interesting keynote this morning.

Claudia Plattner, Head of BSI, gives an engaging talk motivating the importance of IT security, and then skips the two highest ranked questions in the FAQ on the way (honi soit qui mal y pense) :)
