What are Content Credentials (C2PA)?
Short answer
Content Credentials are tamper-evident metadata, based on the open C2PA standard, that record how a photo or video was made and edited, so viewers can check its origin.
What to know
- Some cameras and editing tools can sign media at creation.
- You can inspect signed files at contentcredentials.org/verify.
- Adoption is still partial, so missing credentials don't prove a file is fake.
