Um… that's already a thing [1]:
TL;DR: What is C2PA in 60 seconds
What: An open technical standard for embedding cryptographically signed provenance data inside digital media files.
Who: Created by a coalition founded by Adobe, Arm, BBC, Intel, Microsoft, and Truepic in February 2021.
How: A C2PA Manifest (also called a Content Credential) travels inside the file and records who made it, when, and what tools were used.
Why: Deepfake incidents surged from 500,000 to 8 million cases between 2023 and 2025. Provenance gives media a verifiable chain of custody.
