What is DRM? How Does it Work?


File Protection

If you've just started writing and want to start selling your eBooks the question of eBook file protection is something that affects all authors.





What is DRM? 

Digital Rights Management (DRM) is a standardized approach to copyright protection of digital media such as eBooks.  Basically it's a lock that is placed on a digital file which is tied to the person who purchased it.  Often its applied as a wrapper around the eBook file or part of the packaage of the eBook file.  The valid owner can only open the file if their device or software has the correct key.

Purpose of DRM

DRM is setup to prevent any unauthorised redistribution of digtial media and inhibit the methods that consumers can copy any content they've purchased.  DRM was originally established in response to the illegal distribution of digital media through peer-to-peer file exchange programs.  Within each digital download is an embedded code that prevents copying, stipulating a time period the content can be accessed or cap the number of devices the media can be installed on.

DRM Systems Used in the eBook Marketplace

Currently there are three systems being used by the dominant eBook seller's:

Amazon employs its own DRM to Kindle eBooks, this means you can't sell an eBook directly from your own website.

Apple administers its FairPlay DRM to its files bought from the iBookstore, Just like Amazon its only compatible with its own devices and software.

Adobe's system, Adobe Digital Editions Protection Technology (ADEPT), is presently being used by retailers such as Sony, B & N, Kobo, and Overdrive.
