I have just finished reading an article that my daughter was first author on. “Old Threats, New Name? Generative AI and Visual Journalism

It got me wondering, do #photojournalists use public key cryptography to sign their work? Similarly to how some people use cryptography to sign their emails.
It would provide a way for consumers to distinguish between computer generated images and actual photojournalists work if they were able to digitally sign their images, in a way that #news organisations would honour in their publications. That is, published images or videos would include a digital signature created using public key cryptography. The photojournalist has the private key, and the public key is available online in some photojournalist public key service. So anyone who views the image in a news story can verify that it was produced by the photojournalist using the public key, but of course they can’t sign images with the public key. They can only verify the existing signature. If the photojournalist is the only one that has the private key, they are the only one that can sign the image. Then we would have a way to know which images are real and which are computer generated. Computer generated images won’t have a photojournalist signature unless they wanted them to.
Perhaps this is being done already?
