Digital Rights Management (DRM) is a complex and sometimes controversial topic. There are two unwanted extremes, «all should be free» and «treat users like thieves», and even if you can avoid both of them, there are still many subtleties you should think about. DRM system for digital documents should be strong enough to protect your property effectively but friendly enough not to irritate your users and also flexible enough for many different cases (multiple owners of the same document, resellers, machine-based license, time-based license, etc). OwnerGuard DRM system and PDF OwnerGuard (software which applies this system to PDF documents) are very close to the golden mean.
From the users point of view, there is a very small program, OwnerGuard License Manager. Once it is installed, it will be run only for adding a new license and all licensed documents can be used transparently when they are registered in License Manager. From the owners point of view, PDF Owner Guard is a comprehensive but easy document protector, a license generator and a license manager. It is really flexible in all aspects of DRM.
Licenses can be checked «online» (with real-time requests to your server) or «offline» (by entering a license code you provide). A license can be time-limited and can be attached to a machine or Windows installation; and it is up to you to decide what actions to take on a document (copy, print, capture and so on). Advanced features include reseller management and cooperative creation of license-protected files referring to all creators rights.
