China Subway Facial Recognition System Examined

By: Charles Rollet, Published on Jun 24, 2019

A China city of 6+ million people has installed facial recognition-enabled gates in subways, allowing commuters to enter stations by simply showing their face, thus bypassing ticket/card/phone use. How accurate and efficient is the system?

China Subway Facial Recognition System

In this note, IPVM examines the use of facial recognition for public transit in the PRC. We find that implementation problems persist chiefly due to the systems' use of identification instead of verification, and take a closer look at:

  • System Background & Scale
  • Who Supplies this
  • Purpose
  • How It Works
  • Identification, Not Verification
  • Effectiveness/Issues
  • Government Response
  • Human Rights Concerns
