An NSCAI presentation titled "Chinese Tech Landscape Overview" discusses China's facial recognition CCTV camera network in glowing terms.
"When we talk about data resources, really the largest data source is the government.'"
The presentation discusses how the Chinese government profits from encouraging companies to use facial recognition on visitors and employees.
"Now that these companies are operating at scale they are building a host of other services (e.g. facial recognition for office buildings, augmented reality)"
In America things are not all that different.
In the United States, the Feds encourage private companies like Clearview AI, Amazon Ring and Flock Safety to use facial recognition and automatic license plate readers to identify everyone.
