If you found that tough, you are not alone.

It used to be far easier to spot computer-generated visual creations – often used by fraudsters – because AI would make blunders, like adding an extra finger or something else that was obviously weird.

But AI learns from its mistakes.

“Training on visual artifacts, like looking for a sixth finger or odd earrings, has had limited success, partly because the AI is getting too good, and fraudsters may avoid using pictures with obvious flaws anyway,” explained Prof Amy Dawel.

She is the woman with shoulder-length hair in the picture being held by Sutherland. The man’s image is the fake.

Dawel is the director of the Australian National University Emotions and Faces Lab.

She has been leading a team of researchers in Australia, Canada and the UK to find out if people can be trained to rumble the AI imposters.

The answer, for now at least, is yes – but learning to spot an AI fake requires a more subtle approach.
