Apple and Google partnered to develop contact-tracing technology to help global health authorities to track the COVID-19 spread. With the iOS 13.5 update on iPhone and iPadOS, you can enable or disable the COVID-19 exposure logging on the device.
How Does Contact Tracing Using Exposure Notifications Work?
The exposure notification API uses Bluetooth technology on iPhones to send anonymous identifiers to nearby devices that are within range. Other devices will also broadcast such identifiers and receive them simultaneously. All such identifiers will be stored on the device itself and hence it uses a decentralized approach. Whenever a user manually reports themselves as COVID-19 positive, the data is then sent to everyone who is using a contact tracing app. Then their device will then go through the log of the devices that they had been within their range over the last 14 days. Then inform them if they had come in contact with that COVID-19 positive person. Apple uses a decentralized approach as the logs of the device remain stored on a user’s device.
