Following the development of the Apple-Google contact tracing app

There will be too many stories about the Google/Apple proximity tracing app to list/highlight them all. I’ll update this page from time to time (new items on top) as new developments emerge. If there is anything specifically future focused, like the promise to limit the API’s duration, I will consider a different post.

MIT Technology Review COVID Tracing Tracker

The Project will track and compare various contact tracing apps using five categories:

  • Is it voluntary?
  • Are there limitations on how the data gets used?
  • Will data be destroyed after a period of time?
  • Is data collection minimized?
  • Is the effort transparent?

Change model: better and more comparative information to inform decision-making.


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-3T deployments

Change Model: Privacy-respecting code for contract tracing, built by consortium and focused on decentralized approaches.

“We are a international consortium of technologists, legal experts, engineers and epidemiologists with a wide range of experience who are interested in ensuring that any proximity tracing technology does not result in governments obtaining surveillance capabilities which will endanger civil society.” –

Private Tracer

Private Tracer is open source, privacy by design approach to contact tracing.

Their change model involves creating code that empowers citizens to control and collaborate in tracking their own contacts
