Workspaces
Create workspaces where you can share your credentials with clients and your team. Workspaces also allow you to credential your work together.

How our certificate works
With our Certificate of Provenance, you record that you did not authorize the use of your image, video, or file for Artificial Intelligence and have a document to present if your rights are violated.
Official member of the Content Authenticity InitiativeStep 1
Download the Certificate of Provenance and keep it in a safe location, such as a folder or cloud storage.
Step 2
If you find your image, video, or file being used without authorization or for AI training, gather evidence with our Verifier.
Step 3
Present the certificate along with the evidence when seeking to enforce your rights.
