Antonia Kerle from the BBC talking about https://c2pa.org/ which is basically digital signatures for photos so you can tell an image came from the BBC or from ChattyJeeps or wherever. Provenance to help stop disinformation and deepfakes.

Now they need to create the mindset that unsigned images should be viewed sceptically by default.
