MWITA-CD-2026-035 · Evidence B · P0
A 2026 independent formal-analysis preprint reports that the C2PA specifications it examined did not fully achieve their stated security goals and should not be used alone in high-risk evidentiary contexts.
What this does not establish
The preprint is not a regulator finding, final peer-reviewed consensus or proof that every C2PA implementation fails.
Counterevidence & uncertainty
Revisions, peer review, rebuttals and specification fixes may change the conclusion.
What would change the reading
Update on paper revisions, peer review, author or C2PA rebuttals and security fixes.
