Short answer
A C2PA record can provide verifiable information about an image’s origin and declared editing history. It does not, by itself, prove that the physical product is authentic or the seller is authorised. Brand teams should treat image provenance, signature verification, catalogue matching and sales-channel checks as separate decisions.
Separate image verification from product verification
A marketplace listing may use an official catalogue photo while offering a different product. Conversely, an authorised seller may use a photo they took themselves. A provenance record therefore does not automatically grant permission, and a missing record does not automatically establish infringement. Add separate fields for image provenance and the product’s sales context to the review form.
This distinction is particularly important for product images edited with generative AI. Changing a background, modifying packaging details and placing another product in the same scene are different operations. The team should not only ask whether an image was modified, but also whether the change affects the product information presented to consumers.
A practical review sequence
First record the accessed image version, listing URL and observation time. If the file contains a provenance record, retain the verification tool’s result as a separate attachment. Then compare the image with the organisation’s approved catalogue version. Finally, check consistency between seller, product variant and description. Do not label a product counterfeit before human review is complete.
If verification fails, classify the reason: no record, an unreadable file, lack of support in the tool being used, or a verification inconsistency. Grouping these under a single “invalid” box may present a technical limitation as a commercial risk. Keep each check result with the file version to which it relates.
Pilot acceptance criteria
Prepare a small test set of approved organisational photographs, authorised seller photographs and edited examples. The system should not reach the same verdict for every example; it should read supported records, explain unreadable cases correctly and associate review notes with the relevant file. Measure record-reading accuracy and consistency of human review rather than a percentage of product authenticity.
Implementation checklist
- Are the listing URL and observation time recorded?
- Does the verification result match the file version?
- Which version is the approved catalogue image?
- Was seller authorisation reviewed separately?
- Are uncertain results sent for human review?
Frequently asked questions
Is an image without a provenance record counterfeit?
No. A missing record is a verification limitation; it does not, by itself, establish counterfeiting or infringement.
Is C2PA preserved in the same way by every marketplace?
Do not assume this. Test the platform’s file-processing chain and the verification tool using sample files.
Scope and limitations
This workflow reviews image provenance. Product authenticity, seller authorisation and infringement are assessed separately; no content-removal result or sufficiency of legal evidence is guaranteed.
