comment How to add random lines over text as a watermark and anti-OCR?
BTW, I noticed that the exclusion by \nodrmstart doesn't seem to work when I make paragraphs on the page - e.g. inserting one extra newline before "Pellentesque habitant morbi tristique" to make it a separate paragraph causes the protected region to be drawn on. I've decided to go with mbork's solution, as it's working for me so far.

Whoops, sorry, that was my fault (and my friend's, apparently) - I should update my packages more often. I'm using MikTeX and he uses TeX Live; he probably haven't updated packages in a while either.

I know that objects in the PDF can be manipulated, and that giving out a PDF file with such "protection" would not be a good idea at all. A QR code would not be a good fit - a machine-readable tagging system for documents is not what I had in mind, but rather something more human-readable (or human-recognizable, I suppose), and more tied to the text. However, I was not aware that LaTeX had the pst-barcode package, and it looks interesting, so thanks very much for pointing it out to me!

This does not compile for me, and I had a friend check on a different distribution - it failed as well. Is the snippet exactly what compiles for you? The screenshot suggests that it works perfectly on your end...

Thanks, this does exactly what I had in mind! Oh, and about the drm tag - I thought it would actually fit the best even though it's not really about that.
