C2PA (Coalition for Content Provenance and Authenticity) was formed in February 2021 through the merger of Adobe’s Content Authenticity Initiative and Project Origin, an effort led by Microsoft and the BBC. Its steering committee today includes Adobe, Amazon, BBC, Google, Meta, Microsoft, OpenAI, Publicis Groupe, Sony, TikTok, and Truepic, and the specification is published openly at spec.c2pa.org, currently at version 2.3.<\/p>
The standard’s core mechanism is the Content Credential: a manifest attached to a file that records assertions about its origin and history \u2014 who or what created it, what actions were performed on it (editing, AI generation, compositing), and what earlier assets it was derived from. The manifest is cryptographically signed, so any attempt to alter the file or its history after signing is detectable, and it can reference a chain of prior manifests back through an asset’s full edit history.<\/p>
For a DAM, the practical question is whether the manifest survives the system’s own processing. Most DAMs generate derivatives \u2014 thumbnails, resized web versions, format conversions \u2014 as a matter of course, and unless that pipeline is C2PA-aware, those operations strip the embedded manifest rather than updating or re-signing it. As editorial buyers, ad platforms, and AI-disclosure requirements increasingly ask for Content Credentials before accepting an asset, whether a DAM preserves or discards them on export becomes a real functional gap, not a cosmetic one.<\/p>","protected":false},"excerpt":{"rendered":"
