I think the closest you can come to making it secure is to make use Adobe's Electronic book system. It's a PDF that can be read only in a special application and does not allow for copying at all. The only glitch in the system is
"User makes screenshot, runs screenshot through OCR and has the text back. It can't be done. You can keep honest people honest, but that is it." But I've read an online book with it. I think it will accomplish most of what you are looking to do - casual copying. - Matt Small -----Original Message----- From: Jochem van Dieten [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 29, 2002 9:42 AM To: CF-Talk Subject: Re: OT: pdf Steven Dworman wrote: > Here's the deal.

Generally this protects the complete CD from being copied, not the individual files. It works through one of the executables that is on the CD. Since a .pdf is not an executable and is opened using the executable (Acrobat Reader) from the user I don't think that making the CD copy protected and the file readable will work. > Can this be done? Any solution is a consideration. User makes screenshot, runs screenshot through OCR and has the text back. It can't be done. You can keep honest people honest, but that is it.
