What changes, concretely, in your day-to-day work.
- Make processing transparent.Every intervention on the exhibit is declared, in order, with its author.
- Detect any later modification.An undeclared modification invalidates the signature at verification time.
- Keep exhibits confidential.Nothing is sent to a third-party service: exhibits stay on your infrastructure.
What C2PA does not prove
Transparency is part of the standard. Knowing its limits matters as much as knowing what it can do.
- The truth of what the image shows
- That a human is the author
- Copyright ownership
- Automatic AI detection
Questions
that matter.
Straight answers to the questions we hear most.
Is an exhibit signed by ProvSeal admissible evidence?
ProvSeal provides a verifiable technical history. Its evidential value depends on the context and the jurisdiction: assess it with your counsel.
Does C2PA prove that the scene is real?
No. It documents the declared origin and processing, not the reality of what is depicted.
Can information be redacted without breaking the proof?
Yes, if the redaction is declared: it becomes a step in the history.
