Apple and Google are jointly developing technology to alert people if they have recently come into contact with others found to be infected with coronavirus.

Axar.az reports citing foreign media.

They hope to initially help third-party contact-tracing apps run efficiently.

But ultimately, they aim to do away with the need to download dedicated apps, to encourage the practice.

The two companies believe their approach - designed to keep users, whose participation would be voluntary, anonymous - addresses privacy concerns.

Their contact-tracing method would work by using a smartphone's Bluetooth signals to determine to whom the owner had recently been in proximity for long enough to have established contagion a risk.

If one of those people later tested positive for the Covid-19 virus, a warning would be sent to the original handset owner.

No GPS location data or personal information would be recorded.
