What you're describing is a watermark, not a signature

What I'm describing is a hidden watermark that contains a signature.
A signature over what?
I'm familiar with the concept. A digital signature signs a message. What message are you signing?
If I were creating a verification system, I'd include a Timestamp, camera used, and UUID. If I were selling products to news teams, I'd likely include fields that the firm wanted included like name of company, and if applicable, gps location.
