C2PA Content Credentials
Cryptographic provenance manifests embedded in image, video, and audio files — `who made this, with what tools, edited how`. Adobe, Microsoft, BBC, and the major camera makers ship it.
What it is
C2PA — Coalition for Content Provenance and Authenticity. Defines a binary manifest format embedded in media files containing signed assertions: capture device, edit history, AI involvement, publisher identity. Backed by Adobe, Microsoft, Intel, BBC, Sony, Nikon, Leica, and OpenAI; specification version 2.1 published September 2024.
Why it matters
Provenance is the new credibility signal in an AI-generated content world. Major newsrooms (BBC, NYT) and platforms (LinkedIn, TikTok via experiments) verify C2PA manifests; OpenAI signs DALL·E and Sora outputs. Sites publishing original photography or video gain a verifiable `not AI-generated` signal — and a defense against takedown disputes.
Who it applies to
Publishers, photographers, video producers, and any site whose authenticity matters for trust or compliance.
