Provenance – what can we trust?
With important elections and armed conflicts across the world, trustworthy news is essential to stable democracy. So, whether you are a journalist building a news story for broadcast or a viewer watching news on social media – how can we trust what we see? Our first paper, provides an extraordinarily thorough walk through of the recently standardised Coalition for Content Provenance and Authenticity (C2PA) security and trust system. Illustrating its capabilities by considering cutting a piece of supposed broadcast news and posting it to social media, to identify any gaps and ensure useful provenance information is shown in such situations. Our second paper reports on trials undertaken by the BBC and the Media Cluster, Norway to implement C2PA, including how best to communicate that provenance information to the viewer.
