C2PA was founded by Adobe, Microsoft, Intel, and the BBC to address misinformation and content authenticity at scale. The standard uses cryptographic manifests embedded directly in media files—images, video, audio, and documents—creating a tamper-evident record of how content was created and modified.
For AI-generated content, C2PA manifests can record the generative model, prompt, and parameters used. This makes C2PA the emerging technical foundation for AI transparency regulations. Major platforms including Google, Meta, and OpenAI have committed to supporting C2PA verification.
