Controversial digital contact tracing platforms are now deploying worldwide. the utilization of phones to trace the movements and trace the contacts of many many citizens is unprecedented. it’s also unproven. More worryingly, there’s now evidence to suggest that the approach being taken by most of those apps is wrong. which should raise serious concerns for many users.
Back before Apple and Google announced a joint program to incorporate a privacy-first contact tracing framework in updates to Android and iOS, there was a special debate happening . Would governments use phone network data to trace our movements, without anyone installing an app or opting in? There was even talk about a world standard across the networks themselves.
But then Singapore launched its “Trace Together” platform, making innovative use of Bluetooth proximity tracking and inspiring its citizens to download the app and play along. Pretty soon, countries round the world jumped on the bandwagon and announced plans to launch similar apps.
The only problem is that the initial program in Singapore didn’t work—but that hasn’t stopped the bandwagon rolling along elsewhere.

There are some fundamental problems with Bluetooth proximity technology for contact tracing—capable smartphones, levels of take-up and compliance, accurate distance measurements, and context—am I reception , the opposite side of a wall to you, or are we next to every other during a workplace?
This led to a central versus de-central debate—if a central database of contacts is stored, then virologists and epidemiologists can mine the info for patterns and apply context, detecting hotpots. But that comes at the theoretical price of individual privacy. That database is actually a national level surveillance scheme, and no-one likes the sound of that.
Cue Apple and Google. The tech giants would solve the technical challenges, probably, introducing an OS-level framework on which of these national apps could operate. But these benefits would come at a price. No data might be offloaded from users’ devices. Privacy would come first. Even storing location data would be banned. In a moment , the central versus de-central debate was over. And, as seen within the U.K. et al. in Europe, countries had to compromise so as to possess even an opportunity of creating this work.
Singapore didn’t go along side this—the country with the foremost experience of such apps knew that the Apple and Google model wouldn’t be effective. Even its more privacy-invasive model had failed, forcing it to introduce additional measures to spot which citizens visited which locations at which times.
But elsewhere, the privacy-first approach had won out. As the U.K. discovered, getting an app to figure that didn’t follow Apple and Google’s rules wasn’t possible, suffering too many technical issues. The U.K. development was a multitude in any case, but its decide to go its own way was flawed from the beginning .
All that said, the most issue with these contact tracing apps isn’t technical, it’s behavioral. Not enough folks will install the apps, and, albeit we do, we’ll not suits instructions to urge tested or self-isolate unless mandated to try to to so. An opt-in, anonymized platform cannot enforce or maybe reliably measure.
Quietly, though, one country has been revisiting that initial debate—forget apps, forget Apple and Google laying down rules: Should a rustic make use of network tracking technologies which will operate across the board.
In March, Israeli Prime Minister Benjamin Netanyahu caused controversy by announcing that the country would “use all means to fight the spread of coronavirus… means until today I even have avoided using among the civilian population.” He meant network tracking technologies, which he acknowledged are “usually used for counter-terror,” not on the population.
A month after introducing its use, Israel’s Supreme Court stopped Shin Bet—the country’s domestic intelligence agency—from continuing without new legislation being put in situ . The irony, though, is that within the few short weeks it had been active, this network tracking approach proved very effective in tracing infections. together former Israel intel chief told local media, “the nation of Israel lost the war against coronavirus when the tracking was stopped.”
And so, unsurprisingly, Israel has revisited its decision to show off the potential . “We know this subject is problematic,” Netanyahu told cabinet colleagues last week, “but on the opposite hand, we also know that it contributed greatly to keeping the epidemic in restraint .” And now those ministers have approved the specified draft legislation. “This tool,” Netanyahu said, “will serve us in stopping the spread of this pandemic.”

Israel isn’t alone. Other countries have used surveillance technologies to fight the spread of COVID-19. the thought of such tracking capabilities, a minimum of in Israel’s case, is to work when needed. These aren’t always-on. Instead, when there are spikes or areas of high infection, the potential are often switched on to accelerate contact tracing and apply downward pressure.
And so, because the remainder of the planet begins to put in those privacy-first, opt-in, non-mandatory apps, bear in mind the experience from Singapore and Israel, which suggests we are on the incorrect path. it’ll take months to assess the efficacy and compliance metrics of such apps, and therefore the danger is that it’ll only be if and once we see a large-scale second wave next winter that we’ll know needless to say . But the danger is that we are close to learn a costly lesson.
Meanwhile, the challenge for governments to calm privacy concerns was perfectly illustrated by the viral social media buzz claiming Apple and Google had secretly installed tracking apps on all our phones. The tech giants had done nothing of the type , of course, it had been merely an enabling framework to support any apps we elect to put in . But the purpose was clear.
You can design a tracking program to fight the virus or to safeguard individual privacy concerns. You can’t do both. Perhaps at some point we’ll question why we allowed Apple and Google to form the choice for the remainder folks , instead of the elected governments we hold in charge of what happens next.
