China Subway Facial Recognition System Examined

By Charles Rollet, Published Jun 24, 2019, 07:45am EDT

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?

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

At peak times in Shenzhen the metro's so overcrowded there are long queues, not for the payment barriers but the security check before you even get into the stations.

So the effective use of having them faster is wasted when it is 10minutes just waiting to get to them, and so the waiting time is now irrelevant in the scheme of time saved.

Looks like someone trying to make a product work, where in fact there is no value in the time saved. I would suspect the objective is not for speed but for tracking people.
