'Privacy minefield': India COVID-19 app raises surveillance fears

Indian authorities have made a contact-tracing mobile app mandatory for all public and private sector employees, raising concerns among digital rights experts about privacy and increased surveillance.

Aarogya Setu, the app launched by the Indian government earlier this month to stem the novel coronavirus outbreak, evaluates users' risk of infection based on location, and their medical and travel history. It uses Bluetooth and location services to trace a user's contacts.
