If the idea has spread widely in Europe, digital "tracing" is also making way in France where it could take the form of an application, without any element of identification, allowing to inform a person if he crossed another, contaminated, so that it confines itself again.

The Asian countries have started it and it will soon be Europe's turn to adopt these digital applications making it possible to identify the movements of people suffering from coronavirus. A way for the authorities to get out of the deconfinement without risking a rebound of the epidemic. However, these technologies are causing concern in France because individual freedoms could be cut. What French digital "tracing" could thus be acceptable? This is the question to which Eve Roger answered on Europe 1.

Even if the subject is recurrent in the current debate, the hexagon is still far from the Korean hyper control which has, for example, set up home control and remote sound alerts. In France, this digital "tracking" or "tracking" could take the form of an application to download on our mobile phone and which would not include any identification element, that is to say neither name nor address and which would not indicate our movements either.

However without GPS or geolocation, impossible to know if the French are moving and where, unlike the system advocated by MIT in the United States which would identify areas at risk if several infected people had to regroup.

The need for everyone's informed consent

Thus, the only information that an infected person could give thanks to the bluetooth system of their phone in France, would be their interactions: who did they meet closely and in the 14 days preceding their contamination? And the persons concerned, although we do not know their identity, could therefore be notified via their telephone and confine themselves in turn for 14 days.

Two conditions remain, however. For the CNIL and the digital ethics committee which published an opinion yesterday, all of this could not be done without the informed consent of each and especially that the government fixes from the start the duration of the digital tracing. A period which must imperatively be provisional.
