Apple and Google’s manufacturing teams have banded mutually to build a decentralized contact tracing device that will assist individuals in defining whether they have been in contact with someone with COVID-19.

How Does The App Work? 

Contact tracing is a beneficial tool that assists public health officials in tracking the spread of the virus and notifying the likely exposed so that they can get examined. 

It does this by classifying and “catching up with” people who have got into contact with a COVID-19-affected person.

The initial stage of the project is an API that public health companies can combine into their apps. 

The following stage is a system-level contact tracing method that will work over iOS and Android phones on an opt-in basis.

The system utilizes onboard radios on your equipment to send an anonymous ID across short ranges — applying Bluetooth beaconing. 

Servers send your last 14 days of revolving IDs to different devices, which seek for a match. 

A match is defined based on a start of time consumed, and distance kept between two devices.

If a match is detected with a different user that has informed the system that they have been tested positive, you are cautioned and can take measures to be examined and to self-quarantine.

Bluetooth to build a privacy-conscious contact tracing device that was motivated by Apple’s Find My system. 

The companies state that those companies recognized technical difficulties that they were incapable of overcoming and requested for help.

The project had started two weeks before by engineers from both companies.

Why Are The Companies Working Together? 

One of the causes the companies got included is that there is weak interoperability among systems on several manufacturer’s devices. 

With contact tracing, every moment you fragment a system like this within multiple apps, you restrict its effectiveness considerably. 

You need a huge amount of selection in one system for contact tracing to operate well.

At the same point, you go into technical obstacles like Bluetooth power suck, privacy matters about centralized data acquisition and the absolute struggle it takes to get sufficient people to install the apps to be productive.
