I'm searching if it is possible to set permissions in LaTeX code to prevent copy/print/make changes of pdf? And if it is possible to encrypt pdf in LaTeX code?

  • This may be heavily dependent on the viewer you use, whether the security applied is adhered to. – Werner Dec 14 '13 at 18:05
  • Unless you set a password for opening, such "protection" will be trivial to remove, of course. – Ingmar Dec 14 '13 at 18:07

  • I've seen somwhere here that you can use cmap to destroy te cmapt table on purpose, making it impossible to copy text from the pdf – Martin H Dec 14 '13 at 18:11
  • @Martin H: It should still be possible to save it as an image and to run OCR over it. – Chris Dec 14 '13 at 18:31

    Nice question. But we read everyday nothing is 100% secure with the internet. So always there is a way to break the rule. – Sigur Dec 14 '13 at 18:36
