Apple and Google are working on the way to assist public health officials to track possible COVID-19 coronavirus contacts between users, with strong controls and protections for user privacy.

Apple and Google have stated they are developing a new system to track the transmission of the novel coronavirus, which will assist users share data through Bluetooth Low Energy (BLE) transmissions, and other apps permitted by health organizations, according to a Google blog post.

Apple and Google to develop new coronavirus tracing apps

The new tracking system — which is described in a series of blog posts — will use short-range communications through Bluetooth to establish voluntary networks that trace new contacts and archive broad data on phones that have been in close contact to one another, reports The Verge. Apps put out by public health authorities will also have full entree to the data, and users who download the apps may inform if they have been diagnosed with the COVID-19 illness. The new tracking system will also notify those who downloaded them to check if they’ve been in close interaction with an infected person.

Apple and Google will introduce the pair of APIs for iOS and Android in mid-May, in expectations of giving health authorities’ apps time to organize to implement them. In the upcoming months, both companies will work on building new tracing functionality into the basic operating system, and will then allow users to choose whether they wish to share their health information among a broader range of apps.

One of the most encouraging solutions for containing the COVID-19 outbreak is contact tracing. But there’s a drawback: this kind of watching is often seen as intrusive, and thus raises serious concerns about privacy.

Other tracking methods — like GPS — track people’s real location, but this new tracking method won’t. The Verge reported that it’ll receive signals of close by phones at five-minute intervals, and save the connections between them in a big database. If a user tests positive for the COVID-19 coronavirus, they can tell the app that they’ve catch the illness, and it will inform all other users whose phones have passed within close vicinity in the last numerous days.

The new system will also take many steps to keep people from being identified against their consent, even after they’ve shared their data. While the app checks-in through Bluetooth like clockwork, all information sent is done with an unidentified key, instead of a static identity. Moreover, those keys re-cycle every 15 minutes in the concern of privacy.

Even after a user shares their diseased status, the app will only share keys during the period for which they were transmissible, according to The Verge. The device (Android or iOS) performs all of the cryptographic computation, with central servers only holding a database of shared keys. Thus, there will be no centrally-accessible master list of which phones have complemented, contagious or not.

Though, there’s still a flaw in the method. In packed places, the system might flag people in adjacent rooms who in actuality aren’t sharing space with ill users, at all. Groundless worry could flourish without merit. Moreover, the system might not capture the extent of duration in exposure — walking by a coronavirus-positive user doesn’t equate to spending a day next to an ill coworker.

The program is also novel, which means Apple and Google are still in talks with public health authorities and other stakeholders, to plan how to run the system. It likely can’t replace older methods of tracing human contact, which usually include interviews of infected people about where they’ve been, and who they’ve been close. Though, it might give the world a high-tech emergency.

This is breaking news, so be sure to return here for more progresses.
