The U.S. government’s National Institute of Standards and Technology has been using images of abused children, U.S. visa applicants, dead arrestees, and even travelers boarding aircraft in the U.S. to help train its Facial Recognition Verification Testing program.
What’s more, the agency’s been doing it all without the knowledge of the people in those photographs. Your photo may be one of the ones being used. If so, you probably never gave permission for that use, did you?
The government’s use of these nonconsensual images is not exactly a secret but is never mentioned or publicized by the government.
