Or they could, I don't know, read the research paper for it - https://arxiv.org/abs/2510.09263

As with most standards, there are three almost overlapping standards for image metadata. EXIF, IPTC and XMP. IPTC incidentally is hot again because certain generative AI providers add IPTC metadata[1] to the images they generate. Incidentally, OpenAI uses another standard for the same purpose, C2PA[2]. All of these, the author mentions. Now for SynthID[3], which both OpenAI and Google embed in the pixels of the images they generate. Needless to say, in mutually incompatible ways.

I'm not going to mince words - what you're saying is dangerous and harmful. > to be clear can not track you in any way All they have to do is encode enough entropy for a database unique identifier. Systems like this have been used to do it for audio: https://github.com/swesterfeld/audiowmark SynthID payloads work the same way, and the paper discusses encoding a "user identifier": https://arxiv.org/html/2510.09263v1#S5 All you need to do is encode a database identifier, GeoIP, or other identifying information, and you've violated a person's privacy without their knowledge or consent. Once…

I guess the SynthID-Image paper from Oct 2025[0] was an encoder-decoder for which they tested checking a flag or a 136 bit payload in 512x512 images and the watermark's robustness after various transformations. Presumably the deployed version is meaningfully different. [0]:https://arxiv.org/html/2510.09263v1

The paper they published last year goes over some of these transformations: https://arxiv.org/pdf/2510.09263
