When the notion of enlisting smartphones to help fight the COVID-19 pandemic first surfaced last spring, it sparked a months-long debate: ought to apps gather location knowledge, which may assist with contact tracing however doubtlessly reveal delicate info? Or ought to they take a more restricted strategy, solely measuring Bluetooth-based proximity to different telephones? Now, a broad survey of tons of of COVID-19-related apps reveals that the reply is all the above. And that has made the COVID-19 app ecosystem a type of wild, sprawling panorama, filled with potential privacy pitfalls.
Late last month, Jonathan Albright, director of the Digital Forensics Initiative at the Tow Center for Digital Journalism, launched the outcomes of his analysis of 493 COVID-19-related iOS apps across dozens of countries. His research of these apps, which deal with all the things from symptom-monitoring to telehealth consultations to contact tracing, catalogs the info permissions every one requests. At WIRED’s request, Albright then broke down the dataset additional to focus particularly on the 359 apps that deal with contact tracing, publicity notification, screening, reporting, office monitoring, and COVID-19 info from public well being authorities across the globe.
The outcomes present that solely 47 of that subset of 359 apps use Google and Apple’s more privacy-friendly exposure-notification system, which restricts apps to solely Bluetooth knowledge assortment. More than six out of seven COVID-19-focused iOS apps worldwide are free to request no matter privacy permissions they need, with 59 p.c asking for a consumer’s location when in use and 43 p.c monitoring location at all occasions. Albright discovered that 44 p.c of COVID-19 apps on iOS requested for entry to the telephone’s digital camera, 22 p.c of apps requested for entry to the consumer’s microphone, 32 p.c requested for entry to their pictures, and 11 p.c requested for entry to their contacts.
“It’s hard to justify why a lot of these apps would need your constant location, your microphone, your photo library,” Albright says. He warns that, even for COVID-19-tracking apps constructed by universities or authorities companies—typically at the native stage—that introduces the danger that private knowledge, typically linked with well being info, may find yourself out of users’ management. “We have a bunch of different, smaller public entities that are more or less developing their own apps, sometimes with third parties. And we don’t know where the data’s going.”
The comparatively low variety of apps that use Google and Apple’s publicity-notification API in comparison with the overall variety of COVID-19 apps should not be seen as a failure of the businesses’ system, Albright factors out. While some public well being authorities have argued that gathering location knowledge is needed for contact tracing, Apple and Google have made clear that their protocol is supposed for the particular goal of “exposure notification”—alerting users on to their publicity to different users who have examined constructive for COVID-19. That excludes the contact tracing, symptom checking, telemedicine, and COVID-19 info and information that different apps provide. The two tech firms have additionally restricted entry to their system to public well being authorities, which has restricted its adoption by design.

“Almost as bad as what you’d expect”
But Albright’s knowledge nonetheless exhibits that many US states, native governments, workplaces, and universities have opted to construct their very own programs for COVID-19 monitoring, screening, reporting, publicity alerts, and quarantine monitoring, maybe in half because of Apple and Google’s slim focus and knowledge restrictions. Of the 18 publicity-alert apps that Albright counted in the United States, 11 use Google and Apple’s Bluetooth system. Two of the others are primarily based on a system known as PathCheck Safeplaces, which collects GPS info however guarantees to anonymize users’ location knowledge. Others, like Citizen Safepass and the CombatCOVID app used in Florida’s Miami-Dade and Palm Beach counties, ask for entry to users’ location and Bluetooth proximity info with out utilizing Google and Apple’s privacy-restricted system. (The two Florida apps requested for permission to trace the consumer’s location in the app itself, surprisingly, not in an iOS immediate.)
But these 18 publicity-notification apps had been simply a part of a bigger class of 45 apps that Albright labeled as “screening and reporting” apps, whose features vary from contact tracing to symptom logging to threat evaluation. Of these apps, 24 requested for location while the app was in use, and 20 requested for location at all occasions. Another 19 requested for entry to the telephone’s digital camera, 10 requested for microphone entry, and 9 requested for entry to the telephone’s photograph library. One symptom-logging software known as CovidNavigator inexplicably requested for users’ Apple Music knowledge. Albright additionally examined one other 38 “workplace monitoring” apps designed to assist hold COVID-19-positive workers quarantined from coworkers. Half of them requested for location knowledge when in use, and 13 requested for location knowledge at all occasions. Only one used Google and Apple’s API.
“In terms of permissions and in terms of the tracking built in, some of these apps seem to be almost as bad as what you’d expect from a Middle Eastern country,” Albright says.
Albright assembled his survey of 493 COVID-19-related apps with knowledge from apps analytics companies 41matters, AppFigures, and AppAnnie, as properly as by working the apps himself while utilizing a proxied connection to observe their community communications. In some circumstances, he sought out public info from app builders about performance. (He says he restricted his research to iOS moderately than Android as a result of there have been previous studies that centered completely on Android and raised comparable privacy considerations, albeit while surveying far fewer apps.) Overall, he says the outcomes of his survey do not level to any essentially nefarious exercise, a lot as a sprawling COVID-19 app market the place private knowledge flows in surprising and lower than clear instructions. In many circumstances, users have little selection however to make use of the COVID-19 screening app that is applied by their school or office and no various to no matter app their state’s well being authorities ask users to undertake.
When WIRED reached out to Apple for remark, the corporate responded in a assertion that it rigorously vets all iOS apps associated to COVID-19—together with people who do not use its publicity-notification API—to verify they’re being developed by respected organizations like authorities companies, well being NGOs, and firms credentialed in well being points or medical and academic establishments as properly as to make sure they’re not misleading in their requests for knowledge. In iOS 14, Apple notes that users are warned with an indicator dot at the top of their display when an app is accessing their microphone or digital camera and lets users select to share approximate moderately than wonderful-grained areas with apps.
But Albright notes that some COVID-19 apps he analyzed went past direct requests for permission to observe the consumer’s location to incorporate promoting analytics, too: while Albright did not find any promoting-centered analytic instruments constructed into publicity-notification or contact-tracing apps, he discovered that, amongst apps he classifies as “information and updates,” three used Google’s advert community and two used Facebook Audience Network, and many others built-in software program improvement kits for analytics instruments together with Branch, Adobe Auditude, and Airship. Albright warns that any of these monitoring instruments may doubtlessly reveal users’ private info to 3rd-occasion advertisers, together with doubtlessly even users’ COVID-19 standing. (Apple famous in its assertion that beginning this yr, builders will likely be required to offer details about each their very own privacy practices and these of any third events whose code they combine into their apps to be accepted into the app retailer.)
“Collect data and then monetize it”
Given the frenzy to create COVID-19-related apps, it is not stunning that many are aggressively gathering private knowledge and, in some circumstances, in search of to revenue from it, says Ashkan Soltani, a privacy researcher and former Federal Trade Commission chief technologist. “The name of the game in the apps space is to collect data and then monetize it,” Soltani says. “And there is essentially an opportunity in the marketplace because there’s so much demand for these types of tools. People have COVID-19 on the brain and therefore developers are going to fill that niche.”
Soltani provides that Google and Apple, by permitting solely official public well being authorities to construct apps that entry their publicity-notification API, constructed a system that drove different builders to construct much less restricted, much less privacy-preserving COVID-19 apps. “I can’t go and build an exposure-notification app that uses Google and Apple’s system without some consultation with public health agencies,” Soltani says. “But I can build my own random app without any oversight other than the App Store’s approval.”
Concerns of information misuse apply to official channels as properly. Just in latest weeks, the British authorities has stated it will allow police to access contact-tracing information and in some circumstances problem fines to folks who do not self-isolate. And after a public backlash, the Israeli authorities walked back a plan to share contact-tracing information with law enforcement so it may very well be used in felony investigations.
Not essentially nefarious
Apps that ask for location knowledge and gather it in a centralized approach do not essentially have shady intentions. In many circumstances, figuring out at least components of an contaminated individual’s location history is important to efficient contact tracing, says Mike Reid, an infectious illness specialist at UCSF, who is additionally main San Francisco’s contact-tracing efforts. Google and Apple’s system, against this, prioritizes the privacy of the consumer however does not share any knowledge with well being companies. “You’re leaving the responsibility entirely to the individual, which makes sense from a privacy point of view,” says Reid. “But from a public health point of view, we’d be completely reliant on the individual calling us up, and it’s unlikely people will do that.”
Reid additionally notes that, with Bluetooth knowledge alone, you’d have little concept about when or the place contacts with an contaminated individual might need occurred—whether or not the contaminated individual was inside or exterior, sporting a masks at the time, or behind a plexiglass barrier, all elements whose significance have become higher understood since Google and Apple first introduced their publicity-notification protocol.
All that helps clarify why so many builders are turning to location knowledge, even with all of the privacy dangers that location-monitoring introduces. And that leaves users to sort by way of the privacy implications and potential well being advantages of an app’s request for location knowledge on their very own—or to take the easier path out of the minefield and simply say no.
