Präsentation: Anonymity Assessment at Datentag

Christian Grafenauer and Michael Kolain presented at the Datentag event on the topic of "Anonymity Assessment". The event was organized by Stiftung Datenschutz and focused on data anonymization. The presentation explained the methodology of translating the legal requirements for anonymization into a mathematical equation and derived a quantifiable model for anonymity in a legal sense. It also explored key considerations and techniques related to data anonymization, providing insights and guidance for attendees.

Kickoff Meeting for the DIN SPEC 4997
Privacy by Blockchain Design: A standardised model for processing personal data using blockchain technology

We are currently starting our preparatory work to develop the first standard regarding this topic with the DIN (German Institute for Standardisation). In order for this standard to have a higher outreach, we would like for all stakeholders to be well represented.

In case you want to contribute to this standard as part of the DIN SPEC Workshop (consortium), please send us an email to confirm your interest, including your comments on the scope of the standard (which can be found under "more info" below. In addition, you have to register for the kickoff meeting at and attend the kickoff meeting to become a consortium member.

The DIN SPEC process should end by October 2019 latest, with a release of the standard planned by the end of this year.

A few additional notes from our side:
1) Although the business plan is in German, the standard will be written in English. If the person representing your organisation can be a German-speaker, it would be our preference. However, if not possible on your end, we would also welcome English-speakers and make sure they are included well in all the process (incl. discussions), as we value expertise over language.
2) There will be no participation fees related to this DIN SPEC project, so that you only would have to bear the costs of your own travel/accommodation for the meetings.
3) Participants to the Workshop who actively contribute and vote in favour of the final version of the DIN SPEC will be included as co-authors in the standard.
