Tracking apps useful tool, but raise privacy fears
Print Edition
As governments around the world consider how to monitor novel coronavirus outbreaks while reopening their societies, many are starting to bet on smartphone apps to help stem the pandemic.
But their decisions on which technologies to use 鈥 and how far those allow authorities to peer into private lives 鈥 are highlighting some uncomfortable tradeoffs between public health and protecting privacy.
鈥淭here are conflicting interests,鈥 said Tina White, a Stanford University researcher. 鈥淕overnments and public health (agencies) want to be able to track people to minimize the spread of COVID-19, but people are less likely to download a voluntary app if it is intrusive.鈥
Containing infectious disease outbreaks boils down to a simple mantra: test, trace and isolate. That means identifying people who test positive for the novel coronavirus, tracking down others they might have infected, and preventing further spread by quarantining everyone who might be contagious. That second step requires an army of health care workers to question virus carriers about recent contacts.
Smartphone apps potentially speed up that process by collecting data about your movements and alerting you if you鈥檝e spent time near a confirmed virus carrier.
The more detailed that data, the more it could help regional governments identify and contain emerging disease 鈥渉ot spots.鈥 But data collected by governments can also be abused by governments 鈥 or their private-sector partners.
Some countries and local governments are issuing voluntary government-designed apps that make information directly available to public health authorities. For instance, in Australia, more than 3 million people have downloaded such an app touted by the prime minister.
On the other side, a competing approach under development by tech giants Apple and Google limits the information collected and anonymizes what it pulls in so that such personalized tracking isn鈥檛 possible. The two giants have pushed for public health agencies to adopt their privacy-oriented model.
Germany and a growing number of European countries have aligned with that approach, while others, such as France and the UK, have argued for more government access to app data.
Another big limitation: many people, particularly in vulnerable populations, don鈥檛 carry smartphones.
In Singapore, a large migrant worker population makes about US$15 a day, powers the city鈥檚 previously booming construction industry, and has limited usage of smartphones.
When the Southeast Asian city-state launched its tracing app in March, confirmed COVID-19 cases were well under 1,000. But in early April, a rash of new infections in worker dormitories pushed that to more than 18,000, triggering new lockdown policies.
鈥淚f we can find a way to automate some of the detective work with technology, I think that would be a significant help,鈥 said Nadia Abuelezam, a disease researcher at Boston College. 鈥淚t won鈥檛 be all we need.鈥
