If the file has been copied or created the metadata remains from the computer, it depends on the use you make of it
Hello @user-crypt,
could you please explain what kind of metadata you are referring to and where exactly it would be stored?
Considering what the users TuckerHST and athulin wrote I take it that the kind of metadata I described above doesânt exist. Would you disagree?
@user-crypt Agreed. The op doesn't mention whether the PDF or it's metadata were changed or whether it was just passed along. This does not conflict with previous advice given.Â
If you want to research such systems for artifacts, I suggest you focus on the non-OS components you mention: web upload, download, mail, etc.Â

Since English isn't my mother tongue, I'm not sure whether I understood the post by @user-crypt correctly. Therefore I would be interested to know what kind of metadata user-crypt is referring to exactly. After reading the posts of TuckerHST and athulin I thought the question whether or not the kind of metadata I described in my original post exists was already answered.
To clarify the aspect you mentioned, @taylor : The PDF files described in the example are supposed to be exact copies of one original file and not being edited before being sent across devices via a regular email software. Any changes of their contents or metadata would be unintentional - and whether such unintentional changes would exist and how/whether they could be used to indentify Person B is what interests me.
I regard the part of @athulin 's post you quoted as no answer to my original question but as an (nevertheless interesting) advice to investigate the mentioned components for traces / investigate the file for possible traces caused by those components instead. Am I getting something wrong?
