The federal government is examining three models for the Corona application

DThe federal government has three different technical concepts for the intended Corona application. This stems from a government response to a written question from Anke Domscheit-Berg (left), a member of the Bundestag. Subsequently, the government not only “looks and evaluates” the concept of the European initiative PEPP-PT, which works on a central approach to data storage, but also the rival DP3T approach, which is based on decentralized storage. The government is also evaluating the solution from the consulting firm Accenture used in Austria.

In a first test of a concept for a Corona application with the help of the German Armed Forces, the Federal Government had still relied on the PEPP-PT concept, which had been developed by 130 European scientists, including researchers from the Robert Koch Institute. However, the PEPP-PT project had come under fire in recent days in a heated debate over an appropriate concept of data protection.

Several well-known institutes and scientists abandoned PEPP-PT, including the Helmholtz Center for Information Security and Swiss epidemiologist Marcel Salathé. They accused PEPP-PT of lack of transparency and of wanting to suppress a public debate on the correct approach to a crown application.

Around 300 experts also signed an open letter warning of the risk of surveillance and misuse if data is stored centrally. Most of them support the DP3T concept, which is also endorsed by the TCN Coalition. The TCN Coalition grew out of several federal government hackathon projects #WirVsVirus.
