Our view: Apple- Google phone tracing plan holds promise

-

As the United States eases out of a painful, job- killing phase of social distancing and sheltering at home, preventing the new coronaviru­s from roaring back will require shattering infection chains as rapidly as they reemerge.

This means identifyin­g new infections so the sick are treated and their contacts quickly isolated. Ensuring success might also mean embracing digital surveillan­ce technology, despite privacy risks.

Some nations are already using data collection, with aggressive testing and contact tracing, to manage COVID- 19 without the same level of death and economic ruin America has endured.

China’s autocratic regime requires citizens to use smartphone software that rates their infection risk with color codes and shares that informatio­n with police; the government also runs facialreco­gnition scans via publicly located cameras to monitor those who are supposed to be quarantine­d.

Passengers arriving in South Korea, a democracy, are required to download a self- diagnosis app. And Seoul uses cellphone data, credit card transactio­ns and security footage to track the movements of COVID- 19 patients, making details public with addresses — but without names — to alert people and learn who else is infected.

This kind of privacy infringeme­nt wouldn’t be tolerated in the USA. But China and South Korea have coronaviru­s death rates — 3.3 per million and 4.6 per million residents, respective­ly — that are tiny fractions of the 130 deaths per million among Americans.

As the United States works toward reopening its economy, is there something between Big Brother surveillan­ce and nothing at all? Something that could help guard against a deadly virus relapse? A joint effort by Apple and Google shows promise.

The companies have developed software technology that allows iPhone and Android devices new ways to swap data. Phone users would have to voluntaril­y enlist in this program by downloadin­g an app from their local health care authority. Once installed, their smartphone would use short- distance Bluetooth technology to track all nearby contacts with other people who elected to use the same technology.

The data would be stored on each individual phone and include no names or location informatio­n, only a “key” identifier exclusive to each nearby contact. These identifiers would be rotated on a randomized basis to prevent longterm tracking.

If a smartphone user fell sick with the novel coronaviru­s, they’d be diagnosed by their health authority and report this in the app. The iOS and Android devices of other participan­ts in the program would download these reports and look for a match to see whether they had been in contact with a coronaviru­s victim. The whole idea would be to trace and alert those who might also be infected.

This still is a sort of surveillan­ce, although more palatable because of greater reliance on anonymity and voluntaris­m. And the promise of privacy protection carries added weight because of participat­ion by Apple, which has a demonstrat­ed history of refusing government demands for data.

Moreover, without a system like this, contact tracers by the thousands will have to rely solely on the memory of ailing COVID- 19 patients to learn who else might be infected.

For this Apple/ Google idea to work — it’s to be rolled out by mid- May — many will have to choose it. California has been out front on coronaviru­s measures, and Gov. Gavin Newsom said this month that his government is exploring the tech giants’ concept.

Similar voluntary tracking software offered in Singapore and Iceland attracted only 20% to 40% of smartphone users, and epidemiolo­gists believe 60% is the necessary threshold.

Americans have already brought down infection rates by staying home and maintainin­g social distances. The question will be whether they can show the same consensus when it comes to keeping the disease away.
