I’ve looked for an answer to this, but no joy. I’ll ask here.
I’m making some documents, I want to prove ownership beyond any doubt.
Can I add a hidden or secret watermark or in some way add metadata that names me as the owner of the documents.
I want it to be undetectable, the people who I’ll provide it for will be clueless regarding this sort of thing anyway.
Also, the documents will likely be converted to Microsoft format somewhere along the line.
What do you all think? Can I do this?
