PDF copy protection is one aspect of PDF security and PDF digital rights management and is the process of applying copy protection controls to PDF documents. In PDF DRM systems it is used to:

Prevent users selecting and copying and pasting content into other applications.
Prevent printing and editing of content.
Lock PDFs to authorized devices to prevent users sharing protected PDF files.
Prevent users to forward the PDF files to their friends.
Lock the PDF files to customer's hard disk only, these PDF files can only be read on his system.
PDF documents are locked to authorized devices so they cannot be shared
Keys to unlock protected PDFs are transparently relayed to authorized devices and stored securely.
Content is only ever decrypted in memory.
Dynamic watermarks can be added to documents so that user information is displayed on viewed and/or printed content.
Documents can automatically expire after a given time and that you can manually revoke access no matter where PDF documents reside.
Document use can be logged so that any unusual behaviour can be detected and acted on – e..g. instantly revoking access.
PDFs can be locked to locations so documents cannot be used outside these locations. For example, you may want users to be able to view protected PDF files on their tablet devices but only at the office.
