The title is very misleading. They store some fingerprints of some photos in their server and then they compare them with the fingerprint of the viral images. If the viral image is a variant of the image previously submitted they can spot the difference, even a single pixel difference. (I don't know if the algorithm is robust enough to survive cropping, brightness correction, and other modification that are allowed.) (You can get a single pixel difference detection with MD5, CRC32, sha1, … the difficult part is not overdetection.) They can't get an unknown image and classify it as real or deepfake. |
