France’s privacy watchdog gave the green light Tuesday to a government-backed cellphone app that will alert users if they have been in contact with an infected person.
Use of the app called topCovid will be voluntary, and will keep track of users who had been in close proximity of one another over a two-week period. If any become infected, they inform the platform, which alerts the others.
Privacy defenders have expressed fears that the app marks the first step towards a society under constant online surveillance.
But the CNIL watchdog, which gave provisional approval for topCovid in April, said Tuesday that the app met the legal requirements for privacy protection, with ample safeguards to prevent abuse.
It nevertheless made a number of recommendations to make it even safer, including improving the quality of information provided to users, allowing users to object to information shared, and providing an option for erasing stored data.
The app will not rely on geolocation, but instead use Bluetooth technology which allows mobile phones to communicate with each other over short distances.
The French parliament, which must vote on the rolling out of the app, will debate the matter on Wednesday.
If it says yes, topCovid could be available in app stores from this weekend.
France started re-emerging on May 11 from a two-month lockdown to curb coronavirus spread. Public transport has resumed, though many people are still working from home and most schools have yet to reopen.
Bars, restaurants, and public parks remain shuttered.
The issue of how to track coronavirus spread with mobile technology has sparked privacy concerns in several countries now lifting strict home confinement measures as they hope to kickstart their economies.
As a result of the lockdowns, few people in most countries have been exposed to the virus, and thus do not have immunity and remain at risk of infection, raising fears of a second wave once people start mixing again.
The European Commission has recommended that data harvested through contact-tracing apps be stored only on users’ own phones and that it be encrypted.
