Apple & Google Bluetooth Contact Tracking Protocol

On April 10, 2020, Apple and Google announced that support for the jointly developed contact tracking protocol will appear in the next updates to their iOS and Android operating systems.

The goal of this project is to reduce the spread of coronavirus by tracking contact chains and early detection of new infections with subsequent rapid isolation.

BLE (Bluetooth Low Energy) technology will be used to track contacts.
The principle of operation of this contact tracing protocol is as follows:
