Similarity match. For that you need to understand reflexively how you think and write. It's a fun test to give a person something they have written but do not remember. Most people can still spot it. It's easier with images though. Especially a mirror. For DallE, the test would be if it can discern its own work from human generated image. Especially of you give it an imaginative task like drawing a representation of itself.
