CoviID: new app to avoid future lockdowns

As Georg explains, research shows that COVID-19 is likely to mutate again, which means outbreaks of the virus could become a seasonal occurrence.

This, in turn, means that to act swiftly and avoid total lockdowns – as well as the economic consequences they carry – in years to come, governments must be adequately informed about outbreak statistics in real time.

Using Bluetooth and geolocation, CoviID will be able to track and trace the movements of an individual covering the two weeks prior to their testing positive for the virus.

In terms of being able to prove your status – which will no doubt become necessary for travellers, school children and university students, and for anyone to enter public spaces – the app will enable a verified healthcare professional to attest to your status once you’ve been tested.

“Whenever you want to prove your status, you show a QR code – either saved to your phone or on a piece of paper – and somebody can scan it to receive the information.”

As for incentivisation, Georg says that Discovery Health (a medical insurance provider) with their rewards programme, Vitality, has shown that people respond well to being incentivised for healthy behaviour.

“We can use insights from behavioural economics to nudge citizens to engage not only in good health practices, but also good hygiene practices, including social distancing and self-isolation.”

During an outbreak of the coronavirus, for instance, social distancing and self-isolation could be rewarded. Once the app picks up that you’ve been at home for a few days, for example, you could be eligible to receive discounts from partner companies like grocery stores.

“This will help the government to incentivise people to do the right thing without having to go into full lockdown every time there is an outbreak, which is very costly,” he says.

Privacy is key

Of course, the sensitive nature of this information requires a platform that will allow people to share it in a manner that is safe, secure and prioritises their privacy.

“Designing this kind of app is not rocket science, and we’re not the first or only ones to do it,” says Georg. “The thing that makes us different, however, is the fact that we’ve designed this from a privacy-first perspective.”

The idea of exposing personal information to government agencies through an app would ring alarm bells for most tech-savvy users and adoption would suffer. Some people will go through great lengths to avoid being traced in this manner. Avoidance and consequential lack of adoption leads to faulty or incomplete data, which would ultimately defy the purpose of such an app for public health purposes

However, using blockchain technology, which helps to ensure protection of privacy, Georg and his team have put impressive measures in place to reveal only the most necessary information.

The CoviID app will collect a user’s personal location and infection status, and store it on their phone using a technology called self-sovereign identity – not on a centralised government or private-sector database. This provides the user with full authority and control over who gets access to the data, for what purpose and for how long.

“Privacy is a human right recognised by the United Nations and we cannot sacrifice it in the interest of public health,” says Georg.

Unprecedented collaboration

Since time is of the essence, Georg and his team have had their heads down to release the first version of CoviID within the next three weeks.

“I think we can get through this together and come out stronger on the other side.”

The idea is that eventually the South African Department of Health will be in charge of rolling out the app to users. The researchers are in discussion with various governmental role-players to raise awareness about the project with the goal of first rolling it out in South Africa, but ultimately all over Africa.

The team has also made progress with possible private sector partners and has buy-in from MTN and Standard Bank already.

“Actually, I’ve never experienced such a quick turnaround time on project proposals,” says Georg. “I received email replies from CEOs within a few hours and even on a Sunday morning. Team South Africa is truly coming through this time.”

He says that even though we are entering a time of great challenges and hardship, this spirit of collaboration and cooperation has left him feeling hopeful.

“I think we can get through this together and come out stronger on the other side,” he concludes. “It’s also exciting to think that UCT could make a meaningful contribution during this crisis.”
