"Deep" Metadata

Hello,

I'm not sure where to put this question, but it seems security oriented. So, I'll post here.

Is there such a thing as “deep” metadata?

I know that you can access “superficial” metadata by clicking on the properties option on drop down menus, and there are programs that will let you edit metadata.

But, is it possible for a computer to leave a fingerprint on every file that passes through it?

For example, lets say I compose a word document on my laptop, print it into pdf, upload it online onto dropbox or mega or some similar site, then you download it and save to your usb.

Is it possible for someone to take that file and find a log of everywhere the file has been?

That is, is it possible to construct a history that the file was first a word doc composed on computer 123abc, then converted to PDF on computer 123abc, then uploaded to site xyz, then downloaded on computer fgh345, and finally copied to USB iop456?

Do computers leave unique identifiers on files that pass through them?

Thanks.

The best freeware tools I know of to edit metadata are

I do not think devices add additional metadata to files for every device they have passed through, it really only stores info on the file settings like resolution, camera settings etc and in some cases the type of device the original file was created on such as the type of camera.
