Among the most heralded applications for fighting the coronavirus perhaps the most talked about is the one set up by the German government. We are referring to the Corona Warn App, developed by the Robert Koch Institute and which acts as a tool for tracking possible cases of infection.
Track infections anonymously and break the infection chain
The application works as a tracker for determining who might have been in contact with someone infected with COVID-19. It does this by using Bluetooth and exchanging random codes between devices that are activated. These codes are stored for 14 days, the virus incubation period, and are then deleted. Only when someone voluntarily registers as being infected will those whose codes have been exchanged with those of the infected person receive a warning notification. This tracking is key to breaking the infection chain early on.
As for privacy, which is the biggest concern for many users, the app doesn't store any data and no one knows by whom or where they may have been infected. The app also reminds users to maintain basic hygiene measures and social distancing.
