A Duke study recorded thousands of students’ faces. Now they’re being used all over the world

Jake Satisky:

t was a gloomy day in March 2014. Thousands of students were walking around campus, going to and from their classes, minding their own business.

What they might not have known is that on this particular day, Duke researchers were recording them and putting their likenesses into a data set. This data set would be placed on a public website, and it would be downloaded by academics, security contractors and military researchers around the globe.
