That only works with a image that has been altered.

Not actually recreated.

Think of it like this. You have a painting and you want to alter one detail of it.

You dont redraw the entire painting, you just edit one small part of it. This is easy for a computer to see because there is going to be a break in the pattern of pixels/colors around the edit.

This technique is the equivalent of redrawing the entire image, whether thats to alter one little detail, or to create an entire fake image. For now all we can do is look for the imperfections that the ai leaves. Which may not exist in a few more years.
