A few hours before the press conference of Edouard Philippe and Olivier Veran, the debates continue on the merits of digital tracing in the fight against Coronavirus. On the research side, German and French scientists are making progress and have just published their technical proposal for this system on Saturday April 18.

The researchers also announced their wish that the tracking of people infected with COVID-19 will also be controlled by an independent health authority if the authorities give the green light.

Robert protocol to be subject to parliamentary debate

As reported by our colleagues at France Info, a team of researchers from INRIA (National Institute for Research in Computer Science and Automation) and the German Fraunhofer Institute presented a protocol for detecting contaminated people based on sharing. Thus the protocol, entitled Robert, would allow the sharing of a list of anonymous identifiers corresponding to the people that people who tested positive for CODID-19 could come across during their incubation phase of the virus. This technology would be based on wireless sharing via Bluetooth and would therefore not use the geolocation data of users’ smartphones.

The technical foundation of StopCovid?

Obviously, this project must have the backing of the CNIL to consider a possible use during the start of the containment phase announced by President Macron from May 11. The task of the body will be to validate the authorization of the protocol based on anonymity in the StopCovid application. It seems essential to establish a protocol guaranteeing anonymity in view of the current debate on the threat that the massive use of digital tracing represents for individual freedoms.

This approach based on the consent of the users of the application who tested positive will make it possible to “communicate the history of crypto-identifiers encountered on a server of a health authority without disclosing its own crypto-identifiers”. Thus other users (not tested) could easily check if their own identifiers are among those deemed “at risk”. All this data would be anonymized and under the control of the health authorities so that the “risk” criteria can be reassessed in order to limit the risk of false positives.
