Age Verification in the EU, Ambitious goals, missed privacy opportunities

Protecting minors, today and tomorrow​

The European Commission is preparing a temporary age verification app, aimed at protecting minors on platforms where a minimum age is required—think of online pornography, gambling, alcohol sales, and certain social media services. In a digital world, it's legitimate to shield minors from harmful content. The Digital Services Act (DSA) already obligates large platforms to take protective measures, and the Commission is stepping in where compliance is lacking. A technical solution to verify age online is therefore urgently needed.

As we enter a pivotal phase in digital identity development across Europe, Yivi is committed to becoming a compliant EUDI-wallet. This strategic decision is driven by a broader vision: to ensure that privacy-first identity solutions remain viable in a landscape increasingly shaped by regulation and standardization.

Our mission has always been clear: with Yivi, you are in charge of your digital data. And while regulatory alignment with eIDAS 2.0 and the EUDI-wallet may challenge some of our architectural preferences, it is a necessary step to bring privacy-preserving identity to the masses.

In the night of March 17th to 18th, 2025, at 01:00 CET, we will complete the final phase of the migration from SIDN to Caesar Groep. The last two components that require temporary downtime are the Keyshare Server and MyYivi. These systems play a crucial role in Yivi's authentication and identity management services, and we want to ensure a smooth transition with minimal disruption.

Introduction​

On the 4th of February 2025, version 1.5 of the Architecture Reference Framework (ARF), a crucial document guiding the development and implementation of the European Digital Identity Framework, was released. Given its significance, we conducted an initial review to assess the impact of the changes, particularly in relation to Yivi’s implementation and alignment with the evolving EUDI Wallet ecosystem.

The changes from ARF 1.4 to ARF 1.5 are substantial, introducing new concepts and refining existing ones. Additionally, the list of topics planned for the next version is extensive, covering various key aspects of interoperability, privacy, and security. Looking further ahead, ARF 2.0 is expected to introduce major architectural shifts, likely setting the stage for more definitive long-term structures within the ecosystem.

At Yivi, we are closely following the developments of the ARF and the broader EUDI Wallet ecosystem, ensuring that our roadmap remains aligned with emerging standards and regulatory requirements.

Authentication and identification are critical components of digital services. This can be done with Yivi, our privacy-friendly ID-Wallet. It provides multiple options for verifying user identities. However, a significant challenge in implementing Yivi is the identifier used for authentication. Government and healthcare organizations can use the BSN (Burger Service Nummer), but private entities must explore alternative options. Below, we discuss potential authentication methods using Yivi, their advantages, and their limitations.

January update - Migration announcement

CTO @ Caesar Groep

In our effort to invest in the long-term sustainability of Yivi, we are migrating all Yivi components, including core components, away from SIDN to our reliable hosting environment. Along the way, we are addressing technical debt and implementing improvements where possible.

Additionally, we are collaborating with the Privacy By Design Foundation to migrate critical components, essential to the Yivi ecosystem, away from their servers to our hosting environment. Caesar Groep is taking charge to ensure the foundation no longer runs critical components essential to the Yivi ecosystem.

This blog post outlines the migration's impact. If you are affected in any way or have questions, feel free to contact us.

Hey everyone!

As we approach the end of 2024, our team is working hard to deliver as much progress on the project as possible. In keeping with our commitment to the community, we’re excited to share some of the improvements we’ve been working on. A lot of work has been put into getting a production grade hosting environment, but next to that we also delivered on some other areas.

November update

He all, I thought it would be nice to update you on our progress. Our dedicated team started the development and operations of Yivi effectively on the 1st of November. The existing code base (70+ repositories) is quite large, and the learning curve is rather steep, however I think we are making great progress. We touched a lot of components already and we are learning as we go.

As told during the Yivi meetup we have a roadmap ahead of us containing 3 epics, namely: Cloud Migration, Development and eIDAS2.0. I will update our progress on each of them.
