The way it works

When a person permits the function and has an app from a public well being authority put in, the gadget will usually ship out a beacon by way of Bluetooth that features a random Bluetooth identifier.

If somebody exams constructive for COVID-19, they’ll voluntarily report the constructive check to the Publicity Notification utility for his or her area. These screenshots present public well being authority builders the way to stroll customers by way of the method of reporting that they examined constructive for coronavirus, together with a singular check identifier:

The Publicity Notification API may also likewise obtain an inventory of the keys for the beacons which have been verified as belonging to individuals confirmed constructive for COVID-19, and verify in opposition to that checklist. If there’s a match, the person could also be notified and suggested on the subsequent steps. What constitutes as an publicity? That is as much as the general public well being businesses to resolve, however the API itself features a minimal of 5 minutes of interplay for it to be thought of a match.

Consider it like this: Individual A and Individual B spend greater than 5 minutes collectively at a restaurant. Throughout this time, their smartphones change the nameless Bluetooth identifier. They go their separate methods, however Individual A exams constructive for COVID-19 just a few days later and chooses to report that constructive check by way of the Publicity Notification app. Individual B will then obtain a notification saying that somebody they not too long ago interacted with has examined constructive for COVID-19.
