    Hi,

    I'm new to CD/DVD burning.

    I want to burn some pdf documents into a CD/DVD. Is there a way to make the CD/DVD read-only?

    I don't want the viewers to be able to copy the files over from the CD/DVD into their hard disks.

    I've already put a password into each pdf docs to restrict changes. I'm using Nero 6 to burn, and I also have Sonic 7 installed.

    Thanks a lot for your feedback!

    Yes you can make files read only if you copy to CD/DVD-R not RW.

    Hi CrazyComputerMan,

    Thanks for your reply.

    I have a read me file, a folder called "Thesis-AI" and in that folder there are 15 pdf documents.

    I burnt the above mentioned files into CD-R. I read the CD on another computer; I can still copy the files from the CD and paste it into the hard disk.

    How do I prevent that ?

    Step by step instruction is sincerely appreciated.

    I am still using a much older (4.0) full version of Adobe Acrobat. There is nothing in my version's security settings to prevent Acrobat Reader from using "Save as" to save the currently open document to the hard drive. Unless a newer version of Adobe Acrobat gives you that kind of option, securing the files on the CD itself will be meaningless.

    FWiW: There is commercial software available that makes stripping all of the security settings and password of a PDF file a trivial task that takes milliseconds to complete, even if the security password is not known.

    Unless you're writing top secret documents from NASA, I don't see the point. Commercial software manufacturers don't bother with such protections.

    If someone can open your PDFs, they can save them as new files to their hard drive, or if they really want the data, they'll take screen shots and manipulate the files that way. You're fighting a battle you just can't win.

    Hate to burst your bubble there, but what can be seen can be copied, it's a general rule of digital media.

    If you don't want people to copy your thesis you could put it into a picture and put watermarks all over it that's about the best you can do.

    The watermarks are going to have to be large and complex enough to confuse any OCR programs while still allowing a person to easily read it. Such a watermarking method could be the subject of its own thesis.

    We're all ears. However, just saying there's a solution doesn't make it so.

    I don't see that as a solution to preventing copies. ;)

    If a person can read the text, they can re-type it.

    Where there's a will, there's a way.
