China's government has rolled out a groundbreaking app enabling users to check for potential close contact with coronavirus-infected individuals. Yet, it raises serious ethical concerns around user privacy.
Recent reports highlighted public frustration in China over the epidemic's handling, particularly targeting Wuhan officials. In response, Beijing dispatched a team from the nation's top anti-corruption agency to probe the case of whistleblower Dr. Li Wenliang.
As covered by Xinhua News Agency on February 10, 2020, the government released this state-backed mobile app on February 8. Designed to support public health efforts, it allows citizens to verify if they've been in high-risk situations with COVID-19 cases.
Users scan a QR code to access the app, then input details like name, phone number, and national ID. The tool analyzes this data to flag recent close contacts with infected persons. If positive, it recommends staying home, contacting authorities, and notifies relevant contacts—such as family, friends, or even train staff.
Developed by state-owned China Electronics Technology Group Corporation in partnership with the General Office of the China Council for the Promotion of International Trade and the National Health Commission, the app's reliability remains under scrutiny due to limited transparency beyond Xinhua's announcement.
Dubbed a "close contact detector," it leverages citizens' location and medical data to identify proximity to confirmed or symptomatic cases. This capability underscores its foundation in large-scale surveillance systems.
