India’s contact tracing app, Aarogya Setu, met with another setback as researchers at MIT downgraded its rating from two to one out of five stars. India further lost points on the parameter of “data minimisation”, which means the app collects more data than the information it needs for the purpose of contact tracing.
Meanwhile, technology giants Google and Apple released their “privacy-centric” software tool to enable governments across the world to build their contact tracing applications to counter Covid-19.
Experts say one of the major differences between the technology used by Google and Apple and the one used in Aarogya Setu is that the former does not collect location data. According to Paran Chandrasekaran, CEO and founder of cyber security firm Scentrics, while Aarogya Setu makes use of both Bluetooth and GPS location data, the Google and Apple API uses bluetooth technology, which may have limitations.
