Digital Provenance

With modern AI tools, how do we know which images and videos are real and which ones are generated? Wouldn’t it be helpful to have some digitally verifiable way to tell where something came from and whether it has been altered? Turns out, that technology already exists. It’s open and free to use, and it’s supported by many technology companies. I’ll be digging into all the details of the Coalition for Content Provenance and Authenticity (C2PA) with Jacobo Castellanos from Witness.org.
