C2PA / CONTENT CREDENTIALS IN DEPTH

C2PA is an open standard for cryptographically signed provenance metadata attached to media — who made it, with what tools, and what edits happened. In audio and AI-adjacent workflows it is becoming the mechanism for declaring how a file was produced.

How it works in practice

A signed manifest can record that a track used a specific generative tool at a specific stage.
