I have been very sceptic, but recently some people could give me very interesting and convincing insights. And if even the talk at #38c3 and Anja and Thomas are in favor of this, then it can't be that wrong.

Nice, in-depth article on anonymous-credentials and its challenges:

https://blog.cryptographyengineering.com/2026/03/02/anonymous-credentials-an-illustrated-primer/

Anonymous credentials and the related term zero-knowledge proof are core building blocks for privacy-preserving online age verification.

As I understand, the age verification Australia currently requires to upload a legal document (e.g. a driver's license or government ID), or requires proof by doing a "video self". Both techniques would not be privacy-preserving, because in both cases you are sharing personal information with a company (e.g. Meta).

Cryptography like anonymous credentials solves that problem. At least in theory. You can prove your age, and the other side does not learn anything else about you. Still, to roll it out in real-world scenarios there are many challenges (e.g. dealing with attacks like credential theft).

Side-note: the EU proposal is also built on the same type of cryptography: https://ageverification.dev/av-doc-technical-specification/docs/architecture-and-technical-specifications/

How to protect the OONI dataset from attacks, while preserving the privacy of OONI Probe users?

In our latest blog post, we outline some of the key requirements for OONI's anonymous credential system: https://ooni.org/post/2025-requirements-for-oonis-anonymous-credentials/

#AnonymousCredentials #ooniprobe #ooni

We are excited to share that we are designing & implementing anonymous credentials within OONI Probe to protect and increase trust in OONI data. 🐙🛡️

Here we go again! This time we have a couple of interesting papers on blockchain-related vulnerabilities, an attack against a lightweight stream cipher, an attack against key-store values, a little something about how hard SBOM¹ can be and a couple of hardware security papers.
