A common EU toolbox for contact tracing

“Welcoming the toolbox, Commissioner for Internal Market Thierry Breton said: “Contact tracing apps to limit the spread of coronavirus can be useful, especially as part of Member States’ exit strategies. However, strong privacy safeguards are a pre-requisite for the uptake of these apps, and therefore their usefulness. While we should be innovative and make the best use of technology in fighting the pandemic, we will not compromise on our values and privacy requirements.”

Change Model: Standards and common code

Limiting the Apple/Google Contact Tracer to the Crisis Period Only

“As part of the change, the daily key is now referred to as the “temporary tracing key,” and the long-term tracing key included in the original specification is no longer present.”

Change Model: Code designed for obsolescence?

DP-PPT: a protocol for Decentralized Privacy-Preserving Proximity Tracing

“A group of European privacy experts has proposed a decentralized system for Bluetooth-based COVID-19 contacts tracing which they argue offers greater protection against abuse and misuse of people’s data than apps which pull data into centralized pots.”


Change Model: The promotion of protocols and shared resources to protect privacy.

WhatsApp limits forwards to reduce viral disinformation

While Facebook and YouTube might be changing content moderation approaches, this move by WhatsApp is a structural approach, reducing the number of times a message can be forwarded. Will it stay in place after the pandemic recedes?

It is a powerful change model, as WhatsApp knows it can literally encode (shape) the terms on which speech and ideas can spread between people.

Pan-European Privacy-Preserving Proximity Tracing

“A health crisis must not lead to a weakening of privacy that so many generations before us have fought for.”

“The development of this technology is based on three basic principles. Firstly, it is the result of close European cooperation. Only in this way can we bundle the expertise on the continent in an efficient and targeted manner. Secondly, the technology should be internationally applicable, i.e. interoperable across national borders. In doing so, the technology will facilitate the resumption of international business and personal travel. And thirdly, the technology should be in line with the General Data Protection Regulation (GDPR). “

The change model is based on promoting privacy-protecting standards during the crisis through code and backend service support.
