alt Hacker NewsOut of frustration with SynthID being closed-source with weird dubious ways to verify if an image has the watermark, I created an imperceptible tamper-resistent watermarking tool intended to be open-sourced, where the watermark can be decoded independently and steganographic aspects are impossible as the algorithm is transparent so nothing can be hidden. The intent is for non-corporations to use it as a defense against the use of spying/AI by making it easy for normal people to prove providence, but I have a feeling nowadays most are not going to see it that way so I am unsure if I will release it.

If you just posted your link here with that comment, I’m sure you’d get a bunch of traffic.
How can you prove provenance if anyone can use it? The point of SynthID is that Apple makes the hardware and OS and can reliably insert the watermark/signature between when the camera takes the photo and when it becomes available to any 3rd party software.
Because they have this pathway only they can access, their key and signature can be trusted. I’m not gonna trust Joe Schmoe’s signature that “No I didn’t use AI” unless I already trust Joe Schmoe (and in which case, he doesn’t need a watermark, I’ll just believe him when he says it).
