Mark the good stuff: Content provenance and the fight against disinformation


BBC Blog: “BBC News’s Verify team is a dedicated group of 60 journalists who fact-check, verify video, counter disinformation, analyse data and – crucially – explain complex stories in the pursuit of truth. On Monday, March 4th, Verify published their first article using a new open media provenance technology called C2PA. The C2PA standard is a technology that records 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’.

Content credentials can be used to help audiences distinguish between authentic, trustworthy media and content that has been faked. The digital signature attached to the provenance information ensures that when the media is “validated”, the person or computer reading the image can be sure that it came from the BBC (or any other source with its own x.509 certificate).

This is important for two reasons. First, it gives publishers like the BBC the ability to share transparently with our audiences what we do every day to deliver great journalism. It also allows us to mark content that is shared across third party platforms (like Facebook) so audiences can trust that when they see a piece of BBC content it does in fact come from the BBC.

For the past three years, BBC R&D has been an active partner in the development of the C2PA standard. It has been developed in collaboration with major media and technology partners, including Microsoft, the New York Times and Adobe. Membership in C2PA is growing to include organisations from all over the world, from established hardware manufacturers like Canon, to technology leaders like OpenAI, fellow media organisations like NHK, and even the Publicis Group covering the advertising industry. Google has now joined the C2PA steering committee and social media companies are leaning in too: Meta has recently announced they are actively assessing implementing C2PA across their platforms…(More)”.
