Apple and Google have provided a number of updates about the technical details of their joint contact tracing system, which they’re now exclusively referring to as an “exposure notification” technology, since the companies say this is a better way to describe what they’re offering. The system is just one part of a contact tracing system, they note, not the entire thing. Changes include modifications made to the API that the companies say provide stronger privacy protections for individual users, and changes to how the API works that they claim will enable health authorities building apps that make use of it to develop more effective software.
