An open letter from an assortment of civil rights groups, including Media Alliance, asked university administrators to keep their campuses free of facial recognition.

On March 2, students and faculty at schools across the country will organize to reject facial recognition’s false promises of safety, and stand against the idea of biased 24/7 tracking and analysis of everyone on campus.

Dozens of schools have clarified that they don’t use or plan to use the technology, while about one third have not responded. Three schools—George Washington University, Duke University, and American University—gave vague statements that implied they may have plans to use facial recognition in the future. And UCLA and Tufts University currently use or have plans to use the technology on its campus.

Campuses that have stated they have no intention of using facial recognition include Boston College, Brown University, Columbia University, Colorado State University, Cornell University, Dartmouth College, DePaul University, MIT, Michigan State University, Georgia Tech, NYU, Hampshire College, Kent State University, Rice University, University of Florida, Oregon State University, UPenn, and John Hopkins University. University of San Francisco clarified that it abandoned its controversial facial recognition program in 2016. Activists made multiple attempts to contact every institution on the scorecard. More than 30 schools did not respond after multiple attempts, including Harvard, Yale, Oberlin, Howard University, Ohio State, Reed, and Sarah Lawrence College.
