#pets2026 — Public Fediverse posts

Forscher der FernUniversität in Hagen haben ein Privacy Gateway entwickelt, das sensible Informationen erkennt und anonymisiert, bevor sie an ChatGPT & Co. gesendet werden. Vorgestellt wurde die Studie auf der #PETS2026. #KI #Datenschutz #LLM #Cybersecurity

I'm watching this talk:

Get your Hands off my Hand: Privacy and Bionic Limbs

Privacy talks CAN get scarier, no matter what I expected.

this FTC post came in the comments:

I'm watching this talk:

Transmissions of Hashed Personally Identifiable Information to Third Parties Across Websites

uhhhh YIKES.

I want to read the full paper as soon as possible.

In summary, websites seem to think hashing is the same as encryption and/or anonymization, but IT IS NOT.

I'm attending this talk right now:

"Should Opt-Out Depend on Where You Live? Comparing Mobile Privacy Choices Across Jurisdictions"

The conclusion seems to be "recreate all your phone app accounts with a German VPN IP address so you get real actual privacy."

Yesterday one of the screens showed this quote:

"How do we get more users for anonymous networks?"

This seemed like a wonderful joke to me, anonymous networks don't have *users*, right?

But I think maybe it wasn't a purposeful joke? I'm not sure!

What about the software developers who work on FemHealth apps?

"Users are worried, but we are confused"

I signed up for a lighting talk at #pets2026 so I figured I'd make it into a short blog post:

I'm jumping into a whole new academic field at #pets2026

It's strange to be meeting new people instead of introducing all the new people to everyone else as I did in the Haskell community.

It's fun to be furiously reading the papers and theses and being lost as to what "anamorphic signature" means.

I'm having a blast but my brain is tired every evening.

Wow, they squished the kernel and all the runtime into one single encrypted binary:

#pets2026

22MB OCI runtime

Wow, I gotta learn more about this surprising thing.

Homomorphic encryption[1] benefits from matrix multiplication optimization via SIMD (and probably via GPU and NPU?)

https://petsymposium.org/popets/2026/popets-2026-0040.pdf

Here's a quote from the paper:
"All experiments are executed on a Linux machine equipped with an AMD EPYC 7763 64-Core Processor running at 2.45GHz, and 512 GB of RAM"

Memory use and runtime is still large in my opinion, but improving.

I'm attending #pets2026 in Calgary and I have learned some scary things about Apple and Google tag trackers.
