Cleveland Police Chief Calvin Williams issued a warning to an undisclosed number of masked protesters outside the Republican National Convention: “If you are a member of a group that causes you to have to hide your face, then you probably need a different cause.”
Police claim they have received at least a dozen calls related to concerns about the small groups of black-clad “anarchists” with masks.
So why is Chief Williams so concerned about the face masks? Too early for Halloween?
Nope, facial recognition.
Law enforcement aggressively employs facial recognition technology at events such as the Republican National Convention to identify “persons of interest” and to catalog new persons of interest. Masked faces don’t play as well with the technology (though newer tech can get around some limitations, and iris scan tech needs only to see your, well, eyes. More below.)
With facial recognition, a computer digitizes an image of someone’s face in a way that makes fooling the system difficult, stuff like measuring the distance between eyes, the angle of one’s nose, ear lobe shape and other tough to alter things.
