All 27 member countries of the European Union seem to be ready to adopt the API of tracking contacts made by Apple and Google to effectively combat the spread of the epidemic of the coronavirus.
Last week the european Commission said that all EU countries should adopt the same app, or at least a common standard-known, Pan-European Privacy Preserving Proximity Tracing (PEPP-PT). Initially, it appeared that the EU wanted to develop its own system, but in the end, you may use the API of Apple and Google.
At the moment, however, it seems that the decision has not yet been taken. Chris Boos stated to see benefits in the use of a centralized model, where all data is stored on a server. The API Apple / Google is deliberately a decentralized approach, in which the data are stored only on the device of the user, unless the owner authorises the loading of their codes of contact via Bluetooth.
Probably, the wisest choice would be to use the API of Apple and Google, because it offers the highest standard regarding the protection of privacy, a fact that is not unimportant since you will need to persuade as many people as possible to use this app.
In the expectation of news from the European Union, please note that the company of Cupertino has placed at the disposal of the health authorities, the anonymous data on the mobility of Apple Maps to help them monitor the effectiveness of the measures of blocking currently in force.
