Researchers at the University of Hull recently unveiled a novel method for detecting AI-generated deepfake images by analyzing reflections in human eyes.
Adejumoke Owolabi, an MSc student at the University of Hull, headed the research under the guidance of Dr. Kevin Pimbblet, professor of astrophysics.
In some ways, the astronomy angle isn’t always necessary for this kind of deepfake detection because a quick glance at a pair of eyes in a photo can reveal reflection inconsistencies, which is something artists who paint portraits have to keep in mind.
They used the Gini coefficient, typically employed to measure light distribution in galaxy images, to assess the uniformity of reflections across eye pixels.
The approach also risks producing false positives, as even authentic photos can sometimes exhibit inconsistent eye reflections due to varied lighting conditions or post-processing techniques.
But analyzing eye reflections may still be a useful tool in a larger deepfake detection toolset that also considers other factors such as hair texture, anatomy, skin details, and background consistency.

Since 2021, the anonymous group, Advance Regina, has been running thousands of dollars worth of advertising on social media and billboard campaigns complaining about crime, taxes and city services.
Advance Regina bills itself as “local residents who love our city,” but its website and social media presence provides no names of actual people behind the organization.
In the past, she was the Saskatchewan Party’s director of training and a constituency organizer, and just last year Premier Scott Moe nominated her for the Queen Elizabeth Platinum Jubilee Medal for public service, according to her Facebook page.
Aaron Moore, a political science professor from the University of Winnipeg, said that as cities have grown and their budgets have inflated, this issue of third-party activism and donations has become more important.
“Advance Regina has transitioned to focus on issue-based advocacy, citizen and voter engagement, and promoting awareness of the current council’s poor performance.”
Moore, the University of Winnipeg political science professor, said that while there are stringent rules for third-party advertising in provincial and federal elections in Canada, that’s generally not the case for municipalities.
