The Corona-Warn-App is a useful, digital tool that warns users of high-risk encounters during the pandemic. The processes in the background, however, remain more or less invisible to most users. In a livestream for the virtual Chaos Communication Congress (rC3), Thomas Klingbeil, SAP Solution Architect for the Corona-Warn-App, explains how the app works in the backend.

How does the app communicate with the backend? How is data protection ensured? And how does the risk calculation work? For anyone interested in the technology behind the Corona-Warn-App, Thomas Klingbeil provides answers in this video. He also explains how these aspects influence the overall architecture of the app.
