Facial recognition sunglasses used by Chinese police in Zhengzhou, Henan Province during Chinese New Year.
Facial recognition software has been used in China for quite a while. China has used facial recognition software to scan large gatherings of people in an effort to capture known criminals. The benefit to greater society outweighs all privacy concerns. In North America, we value our privacy and do not want the authorities to accumulate vast amounts of facial recognition data. North Americans believe we should be able to walk around in public and not be recorded for whatever purpose.
