Application de tracking par Bluetooth en cas de contact proche

Having a user of the app scan a QR code (or NFC?) at a location such as a restaurant is also a good idea (proposed by someone else) - it avoids the unintended detections by Bluetooth (as used in present proposals) and is a more conscious/voluntary act. Ensuring the location codes at the restaurant (or any other place where people spend time close to each other) are unique is maybe not so much an issue as the date/time that the code is scanned also makes part of the stored code. The codes could even change every few days, so that the physical location is also anonymised. Also, the app does not need to be contacted (which otherwise means the user must be known, therefore privacy is compromised) - it can poll a list of tagged codes on a server every day or so, to see if any match one stored locally (including a matching timestamp of course) without any need to transfer data back to the server. The infected person and the user of the app can remain fully anonymous: when diagnosed positive as covid-19, the affected user can tell the app to upload the location codes/datestamps of the last N days to the server where they are tagged, so they can be polled anonymously by the app of other users. Uploaded codes should be deleted (or “untagged”) after some days, when they are no longer useful. May be a good idea if the QR is scanned when “checking out” (i.e. paying the bill in a restaurant), so the owner/responsible of the place can encourage its use. A sign in the window of the restaurant (or whatever) could also be used to announce their use of the app, as positive advertising “We are anti-COVID-19 – are you too?”, or similar.

Vérifiez donc ceci, c'est un Belge qui est cryptographe de la KUL qui est dans l'équipe. https://github.com/DP-3T/documents Et même si cela ne sert pas pour tous les Belges ou pour le Covid ça peut servir pour les personnes a risque (personnel médical), les pays pauvres ou la prochaine épidémie de grippe/SRAS/H1n1...

Bonjour Achille, merci pour cette idée! Comme vous le savez, la Belgique a choisi le traçage de contacts de façon manuel, mais vote proposition ressemble au système mis en place en France, et pourrait tout à fait trouver sa place à Bruxelles.
