Since the COVID-19 Outbreak has started in the world, many countries are trying various methods to find the infected people and one of the most used method is using a dedicated app that helps in finding the people that has come in contact with a COVID-19 infected person.
Indian government launched its COVID-19 contact tracing named Aarogya Setu (Health Bridge) in April that offers official information and updates about the Coronavirus and also includes a self-assessment features that allows users to put in their health condition and if they show any symptoms they will be providing steps to follow as per their results on the app.
Massachusetts Institute of Technology (MIT) Technology Review has created a COVID-19 contact tracing app tracker that labels COVID-19 contact tracing apps of all countries that are using them for tracking the infected person. MIT’s app tracker includes apps from 28 countries around the world including India’s Aarogya Setu app.
|Country||App Name||Review (in Stars)||Technology Used|
|India||Aarogya Setu||1/5||Bluetooth, Location|
|Singapore||Trace Together||5/5||Bluetooth, BlueTrace|
|Switzerland||Swiss Contact Tracing App*||4/5||Bluetooth, DP-3T, Google/Apple|
|China||Chinese health code system||0/5||Location, Data mining|
|Estonia||Estonia's App||2/5||Bluetooth, DP-3T, Google/Apple|
|Germany||Corona App*||2/5||Bluetooth, Google/Apple|
|Ghana||GH COVID-19 Tracker||1/5||Location|
|Ireland||HSE Covid-19 App*||1/5||Bluetooth, Google/Apple|
|Turkey||Hayat Eve Sığar||1/5||Bluetooth, Location|
|UK||NHS COVID-19 App*||3/5||Bluetooth|
Aarogya Setu that has been made compulsory for air travel on Thursday that has made researchers make another drop to its rating on the parameter of “data minimization” which was rated to two out of five stars earlier.
Data minimization means that the app collects more data than the information it needs for the purpose of contact tracing.
According to Paran Chandrasekaran, CEO and Founder of cybersecurity firm Scentrics, while Aarogya Setu makes use of both Bluetooth and GPS location data for its contact tracing app, the Google and Apple API uses Bluetooth technology, which may have limitations.
