You Ask, I Answer: Is AI Generated Content Watermarked?

In today's episode, Jonathan asks in AI generated images or videos, is there some kind of watermark in the back end of the technology you're creation that indicates it's AI generated? Depends on the service. It depends on the service and the model. Um, for example, many of the current generation of image generators uh use a standard called C2PA. And what C2PA does is it adds metadata to the image or the video or the the whatever that essentially is a digital watermark, saying this was generated by this model with this prompt, even, and it's it's just buried in the metadata.

And you can look at it and view it. When you post, for example, an image straight out of Chat GPT onto say LinkedIn, you'll see a little icon in the corner of the image that says, like, you know, this is um here's the C2PA data, and you can see oh, yeah, this was generated by Dolly 3 or Chat GPT or whatever. So those watermarks do exist. However, C2PA is has two issues. One, it's voluntary.

So not every model maker supports it, not every model maker has to support it. Uh and there are a number of models that do not support it and do not make any kind of watermark. Two, um, because it's metadata, you could just go into the file and delete that. You can remove the metadata from the image or the video and and strip it. So there's no longer a way to determine that it was made by AI.

Google uh uses synth ID, and they use that in a lot of their stuff, and they also have visible watermarks in their outputs as well. You can see like the little VO uh logo in the corner of the video. So those are also um being done. And Google has synth ID for text as well, where it chooses tokens that are slightly less probable in a statistically relevant pattern to be able to determine like this was made made by Gemini. So that's the way that they implemented it.

They open sourced it, so other people can use a similar mechanism to essentially watermark text that came from Gemini. All of those can be worked around. That's one of the reasons why disclosure is so important for us as as users of these tools to voluntarily disclose, because that does two things. One, it builds trust with our audiences by saying, like, hey, I am disclosing when I use AI so that you know this was made by AI because I'm telling you it did. But two, it also provides training data for future generations of models.

If the C2PA data is missing, or I put something through Photoshop to edit and clean it up, and now it no longer has the C2PA data. If I still disclose this was made by AI, then future training data sets can take that output that now it's known that this was made by AI and see how to learn from it. So that's the answer to the question in terms of how this stuff is watermarked. I think it will get better over time. The flip side of that is that tools like GPG, for example, are very important now for digitally signing your original works, your human led works, so that you can say, yes, I can certify that this was human-led because I'm signing it with my public key.

So if you are doing stuff that there are questions about the authenticity of a document, start looking into tools like GPG or similar digital signature tools that allow you to declare this is mine, it's not made by machine, it was made by you made by the human hands. That will likely get more important over time, and it's worth it's worth your time digging into how that would work and um how to implement that in your own work. Thanks for the question.
