Appendix B. Document Security

Are you concerned that your document may fall into the wrong hands or that readers may try to change your prose? Or maybe you'd like to distribute your document electronically but don't want that document to be printed and possibly distributed to unauthorized users.

Acrobat's built-in security options can prevent unauthorized access, printing, and editing of your PDF files. Secured PDF files stand up to rigorous attempts to bypass their password-protection schemes.
