The Coalition for Content Provenance and Authenticity (C2PA) addresses the prevalence of misleading information online through the development of technical standards for certifying the source and history (or provenance) of media content. C2PA is a Joint Development Foundation project, formed through an alliance between Adobe, Arm, Intel, Microsoft and Truepic.

C2PA unifies the efforts of the Adobe-led Content Authenticity Initiative (CAI) which focuses on systems to provide context and history for digital media, and Project Origin, a Microsoft- and BBC-led initiative that tackles disinformation in the digital news ecosystem.

The C2PA held a major event on January 26, 2022 where policymakers, academics and industry leaders discussed the future of responsible digital media creation, publication and sharing.


The C2PA Specification along with a series of companion documents can be found here. That site offers a “Downloads” menu where PDF versions of each of the documents can be obtained.

Feedback on the specification can be provided in our github issues.
