There is nothing worse than seeing your hard work, research, creativity or otherwise intellectual property being shared by people that avoided paying for the lesson or subscription because it was never copy protected. For one to have any chance of seeing a return on their work, its publishing and distribution needs to be protected to prevent sharing and unauthorized distribution.


That is where DRM comes into play. Short for "Digital Rights Management", DRM can restrict access to media by only allowing users who are approved by the author. Such access can be granted by token file that the PDF reader can find in the same folder, or by call-to-home requests to a DRM server from which an author can manage documents, users, user groups and permissions. Call-to-home DRM is the preferred choice by professionals because it gives them total control over all aspects with immediate effect on any changes made, whereas token files, one downloaded, cannot be changed or revoked.

DRM can identify each user by IP address, MAC address or serial number. Mac addresses vary with the type of Internet connection being used, and IP addresses can be randomly assigned by Internet server providers. But serial numbers are more consistent (never vary) and are the preferred choice for identifying each user.
