Last weekend, Google and Apple announced a large-scale cooperation. In the coming months, they will update the operating system to identify the new coronavirus carriers. When the user's Bluetooth is connected to other devices nearby, the system records who the person is in contact with. According to previous news, the “Pan-European Proximity Surveillance Based on Privacy Protection (PEPP-PT)”, composed of more than 130 research institutions from 8 countries, is compiling various contact tracking proposals, including support from 25 academic researchers The decentralized privacy protection proximity tracking (DP-3T) initiative.
They believe that PEPP-PT can provide a model for protecting privacy when conducting necessary disease surveillance. Claudia Diaz, an associate professor and researcher at Katholieke Universiteit Leuven, the highest university in Belgium, commented: "This system is very good because it does not reveal privacy and it is difficult to extract any meaningful information from visible information. , Because there are only some random keys, no one can understand, unless you interact with me. "Note: Nym is an open source, decentralized, unlicensed agreement. The problems to be solved by the US contact tracking system include how to keep the user's Bluetooth ID truly anonymous, and how to ensure that the Bluetooth data is uploaded to the server, thereby forming a decentralized and open system method.
