Scientists have found a feature of photos that can be added to a list of things to determine if a photo is authentic or a deepfake. Deepfakes are electronically created photos or videos, using AI, that are nearly impossible for untrained eyes to determine if the photo/video is of something real or made-up. There are countless examples online, and perhaps the most deepfaked person is former President Obama.
Using techniques and information learned primarily from astronomers, and how they take and analyze photos of distant galaxies, it turns our that for photos of humans the key is to check out the eyes. In real photos, generally the reflections of light in the eyes should be the same. AI has not learned this correctly - YET - so presently one can check the colors and reflections of eyes, and that can help determine if it is a fake or not.
This is especially important right now, heading into fall elections, when different individuals and groups are trying to smear candidates and get disinformation to go viral online. Deepfakes have become so easy to create that the average person looking at ads and content would likely not be able to tell the difference, making it SO challenging to determine what's real or not.
