How can a camera have access to the signing key and prevent an attacker gaining access to that key?
Also, this would give camera companies (and any entity with leverage over the camera company, including their government) the power to decide what images are ‘true’ in the public’s eye. Companies that control the keys would need to be good at securing the keys.
In a similar way to the way DRM works in stuff like consoles today. And I’m not sure I follow the second problem here. Anybody could create this type of system going forward. But you have to produce hardware to take a picture in the first place, so obviously hardware manufacturers would be the ones to apply this process. The key simply links a photo back to a manufacturer. It doesn’t give companies monopoly on anything.
