Discussion about special ways to protect a PDF

<< < (4/4)

Contro:
I mean "Digital Rights Management" (DRM), i.e. copy protection. Many e-book vendors use it to protect books (although the term DRM is not restricted to e-books). There are several (incompatible) DRM schemes. Essentially, the PDF is encrypted and can only be viewed if the PDF creator allows it. To open a DRM protected PDF one needs a special PDF reader application (usually provided free of charge by the vendor that sells the DRM solution).

2 PDF DRM solutions (both prevent screenshots of a protected PDF):

Drumlin Security (free of charge, at least the last time I looked)
LockLizard (very expensive)

No idea if this is what you're looking for.

Javelin seems to be a DRM files reader, not an utility to produce super protected pdf files.

Drumlin seems also a reader. Are a method to read pdf files when you have the code, but are not the program to protect the pdf o create the pdf protected.

Drumlin ist exactly the software that you need: "The secure versions of PDF files are created using our Drumlinsoftware, which is also free." (cited from http://www.drumlinsecurity.com/)
