Content Credentials

The consumer-facing name for C2PA provenance metadata — the "nutrition label" platforms read to apply AI tags.

Content Credentials is the public-facing brand for the C2PA provenance standard — the "CR" pin you see on images in tools like Photoshop, and the manifest platforms read to decide whether to show an AI label. Think of it as a tamper-evident nutrition label that records who or what made an image and every edit since.

When an AI generator like DALL-E 3 or a Firefly model creates an image, it can attach a Content Credentials manifest stating the content is AI-generated. Cameras like the Leica M11-P attach one stating the image came from a real sensor. The manifest is cryptographically signed, so platforms can trust it hasn't been altered.

This is the easiest AI signal for platforms to act on, because they don't have to run a classifier — they just read the manifest. Instagram, TikTok, LinkedIn, and others use Content Credentials presence as a trigger for their AI labels.

It's also the easiest signal to remove: the manifest is metadata, not baked into the pixels. SynthGuard strips Content Credentials (C2PA) before any pixel-level processing. But because metadata stripping alone doesn't defeat pixel-level classifiers or invisible watermarks like SynthID, it's only the first step in the pipeline, not the whole job.
