Adding watermark on (PDF)Files at download time

Adding watermark on (PDF)Files at download time

Hi folks,

I'm trying to find a way for putting a watermark on files in the database. The watermark is supposed to be added on the fly as it should be added when a user is downloading a file from the database. It should contain text only (like branding the PDF with the institution and username/ip adress/downloadtime). I have been looking at fpdf and tcpdf in order to use this for my purpose but I did not get very far with that. I understand that this would mean replacing the file field as this allows the immediate download without a watermark being added. Does anybody have some exprience regarding this subject?

Any help is greatly appreciated!

The file download routine hands off to the individual "parent" plugin to get the file. So, it would be possible to write a resource plugin to do this. 

Seems a bit pointless. If people are going to 'steal' your stuff they aren't going to care much about a watermark. And I wonder how easy it would be to remove it again?
