Want to spot a deepfake? The eyes could be a giveaway

Clues to deepfakes may be in the eyes.

Researchers at the University of Hull in England reported July 15 that eye reflections offer a potential way to suss out AI-generated images of people. The approach relies on a technique also used by astronomers to study galaxies.

In real images, light reflections in the eyeballs match up, showing, for instance, the same number of windows or ceiling lights. But in fake images, there’s often an inconsistency in the reflections. “The physics is incorrect,” says Kevin Pimbblet, an observational astronomer who worked on the research with then–graduate student Adejumoke Owolabi and presented the findings at the Royal Astronomical Society’s National Astronomy Meeting in Hull.
