“In principle, the concept of a « Corona App » involves an enormous risk due to the contact and health data that may be collected. At the same time, there is a chance for « privacy-by-design » concepts and technologies that have been developed by the crypto and privacy community over the last decades. With the help of these technologies, it is possible to unfold the epidemilogical potential of contact tracing without creating a privacy disaster. For this reason alone, all concepts that violate or even endanger privacy must be strictly rejected. In the following, we outline social and technical minimum requirements for such technologies. The CCC sees itself in an advisory and observation role in this debate. We will not recommend specific apps, concepts or procedures. We however advise against the use of apps that do not meet these requirements.”
