New York, June 9 (IANS) Researchers, including one of Indian-origin, have found that most of the COVID-19 apps required access to users' personal data, but only a handful indicated the data would be anonymous, encrypted and secured.
Published in the journal Nature Medicine, the study revealed that mobile apps are helping track the spread of COVID-19 to contain the outbreak, but the apps also raise concerns about personal privacy.
“What is disconcerting is that these apps are continuously collecting and processing highly sensitive and personally identifiable information, such as health information, location and direct identifiers, the researchers from the University of Illinois at Urbana-Champaign in the US, wrote.
“Notably, surveillance mapping through apps will allow governments to identify people's travel paths and their entire social networks,” they added.
For the findings, professor Masooda Bashir and doctoral student Tanusree Sharma analysed 50 COVID-19-related apps available in the Google Play store for their access to users' personal data and their privacy protections.
Bashir and Sharma found that most of the apps required access to users' personal data, but only a handful indicated the data would be anonymous, encrypted and secured.
The functionalities of the Covid-related apps developed around the world include live maps and updates of confirmed cases, real-time location-based alerts, systems for monitoring home isolation and quarantine, direct reporting to the government of symptoms and education about COVID-19.
Some also offer to monitor vital signs, virtual medical consultations and community-driven contact tracing.
Of the 50 apps the researchers evaluated, 30 require users' permission to access data from their mobile devices such as contacts, photos, media, files, location data, the camera, the device's ID, call information, Wi-Fi connection, microphone, network access, the Google service configuration and the ability to change network connectivity and audio settings.
Some of the apps state they will collect users' age, email address, phone number and postal code; the device's location, unique identifiers, mobile IP address and operating system; and the types of browsers used on the device.
Only 16 of the apps indicated such data will be anonymous, encrypted, secured and reported only in aggregate form.
Of the apps sampled, 20 were issued by governments, health ministries and other such official sources.
They acknowledged that mass surveillance measures may be necessary to contain the spread of the virus.
“Health care providers must absolutely use whatever means are available to save lives and confine the spread of the virus,” the authors wrote.
“But it is up to the rest, especially those in the field of information privacy and security, to ask the questions needed to protect the right to privacy,” they noted.
