C2PA metadata
Marketing organizations are more concerned than ever about content transparency, AI disclosure, and preventing the tampering of assets. The Content Authenticity Initiative (CAI) at Adobe builds tools compliant with the Coalition for Content Provenance and Authenticity (C2PA) technical standard. C2PA metadata is encrypted, tamper-evident information that helps viewers to understand the lineage of content and ensure the integrity of brand assets. This information includes:
- Issuer or Signer - Information about the entity or company that issued the digital signature to certify or sign the asset.
- Issue Date - The date on which the C2PA metadata was applied to the asset.
- Credit and Usage - Information about the producer of the asset, including name, social media handles, or other identity-related information.
- Process - Records of any edits or modifications made to the asset.
- Device Details - Information about the app or device used to create or edit the asset.
- AI Tool Used - If generative AI was used to edit or create the asset, the name of the model used may be included.
- Other Pertinent Information - Additional data may also be included to help offer more context about the history of an asset.
For comprehensive information about the asset history, you can use the Adobe Content Authenticity inspection tool.
C2PA metadata persists with the image file. When an image that was generated or edited with generative AI is uploaded to or exported from Adobe Journey Optimizer B2B Edition, its C2PA metadata is preserved.

C2PA metadata persistence through channels channels
When you include images in your email or WhatsApp messages, the C2PA metadata for the delivered images is also persisted:
- Email - When you use a Send email journey action, add the image to your email content from the Assets library. When the email is delivered, the recipient can download the image from the message and the C2PA metadata is intact.
- WhatsApp - Add the image to your WhatsApp message template in your Meta business account. You can add it directly from your own system, or download an image file from the Assets library. Use the template for a Send WhatsApp journey action. When the WhatsApp message is delivered, the recipient can download the image from the message and the C2PA metadata is intact.
Actions that affect C2PA metadata cc-workflows
When you generate or edit an image with generative AI tools in Journey Optimizer B2B Edition, C2PA metadata is automatically attached to that image and no action is required on your part.
Generate an image generate
Example: Generate a banner image for an email from a text prompt describing the desired visual. C2PA metadata is attached to the generated image.
When you create a new image from a text prompt, from a reference image, or generate a similar image, C2PA metadata is always attached.
Crop an image crop
Examples:
- Crop a generated banner image to fit a web page. The C2PA metadata is preserved through the crop.
- Use an uploaded stock photo as an email background and crop it to fit the screen. If the stock photo carries no generative AI information, C2PA metadata is not created.
When you make an adjustment to an image file, such as cropping it to requested dimensions, it retains its C2PA metadata only if the source image already had it. Cropping recreates the image pixels, which normally removes that C2PA metadata, so AI Assistant reads it from the source image before cropping, then recreates and re-attaches it to the cropped result. Cropping itself does not add a new generative AI action; it preserves the existing one.
Add a text overlay
Example: Produce a promotional headline as a text overlay on a generated background image for a landing page. The C2PA metadata from the background image is preserved.
When you render generated text on top of a background image, C2PA metadata is attached in the resulting image only if the background image already had C2PA metadata. Rendering the overlay produces a new image, so the image editing tool reads the C2PA metadata from the background and re-attaches it to the result. The overlay step does not add a new generative AI action.
Overlay an image
Examples:
- Create an email header by combining a generated product image with a generated background. The result carries C2PA metadata reflecting both generative AI sources.
- Combine two uploaded brand photos into one collage image. Since neither source image carries a generative AI action, C2PA metadata is not created.
When you composite two or more images together and any of the source images have C2PA metadata, the combined image retains it, merged into a single C2PA metadata element. Compositing produces a new image from the sources, which normally removes that C2PA metadata. But the image editing tools read the source metadata before compositing, then build a single combined C2PA metadata element that lists every source that contributed a generative AI action.
