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.

TOKYO – Vice foreign ministers from Japan and China held a strategic dialogue Monday for the first time in four and a half years, as the countries focus on shared interests amid a host of diplomatic challenges.
Masataka Okano and Chinese counterpart Ma Zhaoxu discussed developments in the East and South China seas as well as Ukraine during their talk in Tokyo.
Other topics included Japan’s release of treated wastewater from the stricken Fukushima Daiichi nuclear power plant and the detention of Japanese nationals in China.
Japanese Foreign Minister Yoko Kamikawa and Chinese counterpart Wang Yi are considering holding talks on the sidelines of ASEAN-hosted meetings in Laos starting Thursday.
China is eager to bolster ties with Japan ahead of the U.S. presidential election in November, concerned that a harsher stance by Washington could lead Tokyo to follow suit.
Beijing also awaits the outcome of the leadership race in Japan’s ruling Liberal Democratic Party scheduled for next month, which will decide the country’s next prime minister.
