I have a PDF to send to someone, but I'd like to be pretty sure they can't change it. Are there any easy solutions to this? Encrypting it is likely to be too much work.
It's going to be a scan, not saving to PDF from a webpage, Word document, etc.
Yeah, that's what I figured. Security by obscurity, it is. – Benjamin Oakes – 2010-03-05T20:02:35.700
