It would work by assessing the closeness and length of contact between people and, should a person test positive for Covid-19, tell recent contacts to call a doctor, get tested or self-isolate.
The numbers that identify users will be randomly generated, and so-called "metadata" such as Bluetooth signal strength and users' phone models will now be encrypted along with primary data about whom they have been near.
Secondly, Apple and Google announced that the metadata associated with Bluetooth will be encrypted, making it more hard for someone to try and use it to identify a person, "for example, by associating the transmit power with a particular model of phone" or the version number of the protocol the phone is running.
As per an Apple representative, the company now releases a FAQ section which is related to the app.
The Bluetooth technology will enable users to be notified if they crossed paths with a coronavirus carrier, but will not specify where the encounter happened, information crucial to authorities who want to identify hotspots for virus transmission and move fast to stop outbreaks. Those phones would be able to interact with each other regardless of operating system thanks to the API that Google and Apple are developing. The OS-level API would allow interoperability between iOS and Android and will allow public health authorities, universities, and NGOs around the world to develop opt-in contact tracing technology. "If the contact is longer than 5 minutes, the system will report time in increments of 5 minutes up to a maximum of 30 minutes to ensure privacy".
Contact tracing is an epidemiological technique that health professionals use to track down anyone an infected patient has come in contact with.

As mentioned before, this contact-tracing feature relies on Bluetooth Low Energy (BLE) to trace the user's interactions. They are working together to develop a framework for the use of Bluetooth on Android and iOS devices for the tracing.

Meanwhile, 6,680 people have recovered from COVID-19, the disease caused by the virus, which is 51.9 per cent of cases. She is at the West Park Long-Term Care home in Etobicoke that has had 13 coronavirus-related deaths.

It also allowed for some moving pictures of those healthcare workers to be displayed on the side of the video as he performed. The special aims to pay tribute to those on the front lines of the coronavirus fight and raise awareness about staying home.
Of course, one of the important steps to encouraging people to do so is to assure them that participating won't put their personal health information at risk.
Proximity identifiers obtained from other devices are processed only on the device and users decide whether to contribute to the exposure notification. These people can then be asked by the health authorities to take appropriate security measures, e.g. Google and Apple will also be unable to trace individual users, under the plan.
Importantly, Apple's iPhone would under the proposed setup only work properly with decentralised protocols such as DP-3T, which has been developed by a Swiss-led team and has been backed by Switzerland, Austria and Estonia.
Other phones will wait for these beacons and will send theirs.
Authorities say the app will be available in the coming weeks.
Each device compares the list of recorded beacons with the list downloaded from the server.
The technology does not use Global Positioning System location information and stores the most sensitive information in a distributed way on users 'phones.
