Level 3 verification · PI Camera

Shoot.
Sign.
Prove.

Every frame is C2PA-signed at the moment of capture and anchored on Bitcoin — before it leaves your phone. Not AI-generated. Not tampered. Provably real.

Key features

What makes PI Camera different.

Not a filter. Not a watermark. Cryptographic proof embedded in the file before it's ever shared.

📸

C2PA signed at capture

The moment you press the shutter, a cryptographic C2PA manifest is embedded. Who shot it, when, where — immutable.

₿

Bitcoin timestamping

The file hash is anchored on Bitcoin via OpenTimestamps. Independently verifiable without trusting any server.

Linked to your verified profile

Every photo or video ties directly to your TETA+PI entity. AI agents see both the content and who created it.

🤖

AI agents can query it

After capture, content is live on your MCP endpoint. Agents can ask: "Is this real? Who made it? When?" — and get a cryptographic answer.

How it works

From capture to proof in seconds.

Open PI Camera and shoot

The app uses your phone's camera. You see a live indicator that C2PA signing is active. No settings needed.

C2PA manifest is generated

Immediately on capture: your identity, timestamp, GPS, and device fingerprint are embedded in a signed C2PA manifest inside the file.

File hash anchored on Bitcoin

The file's SHA-256 hash is sent to OpenTimestamps and committed to Bitcoin. Proof is independent of TETA+PI servers.

Content goes live on your MCP endpoint

Your verified profile is updated. AI agents querying teta_verify_entity now see the content and its full proof chain.
