Advancing content provenance for a safer, more transparent AI ecosystemOpenAI

Quoted passage Building the trust ecosystem through C2PA conformance (para 1)

OpenAI has been engaged in the development and adoption of provenance standards since 2024, when we began adding Content Credentials to images generated by DALL·E 3 […] We also joined the Steering Committee of the Coalition for Content Provenance and Authenticity (C2PA), the cross-industry group behind the open technical standard for content provenance.

Quoted passage Expanding our image detection tools as we build new features (August 4, 2024 update)

As users can now edit DALL-E 3 generated images in ChatGPT, we wanted to ensure that provenance information continues to be demonstrated along with those edits. If a user edits an image, we’ve built in a means for our C2PA credential to show that the image was edited and how. In the example image, you can see the original AI-generated picture of a caterpillar, then edited to have the caterpillar wearing a Santa hat. When a user edits this image, the C2PA credentials update to reflect these changes, ensuring transparency. The C2PA credential includes details like the app and tool used (OpenAI’s DALL-E), the actions taken (like format conversion and edits), and other modifications.
