In October 2024, 70 people representing 30 organisations from 15 countries across four continents gathered at the BBC building in Salford to join the Origin Media Provenance Seminar. The seminar was organised by BBC R&D with partners from Media Cluster Norway (MCN) in Bergen.
Media provenance is a way to record digitally signed information about the provenance of imagery, video and audio – information (or signals) that shows where a piece of media has come from and how it’s been edited. Like an audit trail or a history, these signals are called ‘content credentials’, and are developed as an open standard by the C2PA (Coalition for Content Provenance and Authenticity). Content credentials have just been selected by Time magazine as one of their ‘Best Inventions of 2024’.
Attendees came from all over the world, including the US, Japan, all over Europe, and also sub-Saharan Africa.
According to the BBC blog post:
In order for news organisations to show their consumers that they really are looking at some content from the real “BBC”, content credentials use the same technology as websites – digital certificates – to prove who signed it. The International Press Telecommunications Council (IPTC) has created a programme called “Origin Verified News Publishers”, which allows news organisations to register to get their identity checked. Once their ID has been verified, they can get a certificate, which gives consumers assurance that the content certifiably comes from the organisation they have chosen to trust.
For more information about the event, see the blog post on the BBC Research & Development blog.

AMSTERDAM, 13 September 2024 — The International Press Telecommunications Council (IPTC) has announced Phase 1 of the IPTC Verified News Publishers List at the International Broadcast Convention (IBC).
The list uses C2PA technology to enable verified provenance for the news media industry. News outlets apply for a certificate from a partner Certificate Authority (currently Truepic), with the IPTC verifying the identity of the publisher. The certificate is then used by the news outlet to sign content, in accordance with the C2PA specification’s handling of “additional trust anchor stores”. This means that the news publisher is the signer of the content. This is a key requirement for many media outlets.
Currently the BBC (UK), CBC / Radio Canada (Canada) and broadcaster WDR (Germany) have certificates on the Verified News Publishers List. Many more publishers and broadcasters are currently in the process of obtaining a certificate. To register your interest as a news publisher, please fill out the Verified News Publisher expression of interest form.
To make the process of verifying and approving certificate requests transparent and accountable, the IPTC has released a set of policies for issuing Verified News Publisher certificates covering Phase 1 of the project. The process includes a “fast track” process for media organisations that are already well known to IPTC, and also a self-certification track. The policies were approved by the IPTC membership at a recent meeting of the IPTC Media Provenance Committee.
Verifying publisher identity, not trustworthiness
Note: as we have always made clear, the IPTC is making no claims about the truth or trustworthiness of content published by news publishers on the IPTC Verified News Publisher List. We simply verify that the publisher is “who they say they are”, and then the signature will verify that the content was published by that publisher, and has not been tampered with since the point of publishing.
We make it clear in the governance policies that a certificate can be revoked if the certificate’s private key has been compromised in some way, but we will not revoke certificates for editorial reasons.
Online verifier tool
The IPTC has worked with the BBC to launch a simple Verified News Publisher content verifier tool hosted at https://originverify.iptc.org. The tool displays a special indicator when content has been signed by an organisation whose certificate is on the Verified News Publisher list. The IPTC has also published a set of Verified News Publisher sample content that can be used with the verifier to demonstrate the process in action.
Sharing best practices, resources and knowledge among news publishers
For IPTC members, the Media Provenance Committee has created an internal members-only wiki detailing best practices and lessons learned while implementing C2PA and the Verified News Publisher List at broadcasters and publishers. Information on the wiki includes technical details on how to generate a certificate signing request to obtain a certificate, how to sign content with open-source and commercial tools, how to deal with publishing and distribution technology such as streaming servers and content delivery networks, and how to add metadata to C2PA assertions embedded in media content.
The Committee has also created a public-facing area of the IPTC site describing IPTC’s work in the area of Media Provenance, helping news publishers to get up to speed and understand how C2PA technology works and how it can be implemented in publishing workflows.
