It will be relatively easy to strip that stuff off. It might help a little bit with internet searches or whatever, but anyone spreading deepfakes will probably not be stopped by that. Still better than nothing, I guess.
You can use things like steganography to embed data into the AI output.
Imagine a text has certain letters in certain places which can give you a probability rating that it's AI generated, or errant pixels of certain colors.
Printers already do something like this, printing imperceptible dots on pages.
Having an unreliable verification method is worse than nothing.
How so? If it's anything like llm text based "water marks" the watermark is an integral part of the output. For an llm it's about downrating certain words in the output, I'm guessing for photos you could do the same with certain colors, so if this variation of teal shows up more than this variation then it's made by ai.
I guess the difference with images is that since you're not doing the "guess the next word" aspect and feeding the output from the previous step into the next one, you can't generate the red green list from the previous output.
