India has released the source code of its contact-tracing app, Aarogya Setu, to the relief of privacy and security experts who have been advocating for this ever since the app launched in early April. From a report: Ministry of Electronics and Information Technology Secretary Ajay Prakash Sawhney made the announcement on Tuesday, dubbing the move “opening the heart” of the Aarogya Setu app to allow engineers to inspect and tinker with the code. The app has amassed over 114 million users in less than two months — an unprecedented scale globally. The source code of Aarogya Setu’s Android app is live on GitHub with code of iOS and KaiOS apps slated to release in a “few weeks.” Nearly 98% of the app’s users are on the Android platform. Sawhney said the government will also offer cash prizes of up to $1,325 to security experts for identifying and reporting bugs and vulnerabilities. “Open-sourcing Aarogya Setu is a unique feat for India. No other government product anywhere in the world has been open-sourced at this scale,” said Amitabh Kant, chief executive of government-run think-tank NITI Aayog, in a press conference today.
