C2PA Certification Authority
Tauth is a Certification Authority for the C2PA ecosystem. We issue Content Credential signing certificates, maintain the policies that govern them, and help organizations deploy provenance across their content pipelines.
What is C2PA?
The Coalition for Content Provenance and Authenticity (C2PA) is an open technical standard that binds cryptographically verifiable provenance, including who made a piece of content, how, and with what tools, directly into images, video, audio, and documents.
Content Credentials
Tamper-evident metadata manifests, cryptographically signed at capture, edit, and publish time, that travel with your content wherever it goes.
Certification Authority
As a CA on the C2PA trust list, we vet subscribers, issue signing certificates, and operate the PKI that makes Content Credentials verifiable worldwide.
Conformance & Trust
The C2PA Conformance Program validates generator and validator products, so credentials signed under our certificates are trusted by every compliant verifier.
