![]() Generally DRM uses a server to administer the DRM scheme. Some formats, most notably MOBI have a restriction on dedicated reading devices that they will not permit their software to be used on a dedicated reading device that supports other formats using DRM, although more general devices with eBook reading applications that are loadable can often have MOBI and other reading programs. Some eBook formats do not support DRM and even if a format supports it there may be eBooks in that format that are not controlled by DRM.Ī given reading device may have multiple DRM schemes for the various formats it supports. Some opponents call it Digital Restriction Management and claims it goes far beyond illegal activity and restricts items that are both legal and reasonable use. There is no standard implementation for DRM.ĭRM is supposed to protect the author and publisher of eBooks (or eMusic and other electronic media) from pirating and other illegal activities. The code may be locked to a particular device, or may be locked to a range of multiple devices. DRM as applied to eBooks is generally a code that must be present in order for the reader to be able to open an eBook.
