Digital Rights Management (DRM), sometimes known as content or copy protection is a generic term for access control technologies that can be used by hardware manufacturers, publishers, copyright holders and individuals to try and impose limitations on the usage of digital content and devices.
DRM does not stop copyright pirates but instead interferes with fans use of music, movies and copyrighted works.
It prevents you from making back ups of DVDs and remixing amongst other things.
DRM is also backed up by the Digital Millennium copyright act.
DRM in Music
Many online music stores employ DRM to restrict usage to music purchased and downloaded online. There are music options for consumers wishing to purchase digital music over the internet:
The Itunes Store run by Apple Inc allows users to purchase tracks on line for 99p and is available completely DRM free. Videos sold and rented through itunes, as well as mobile software sold through the Itunes App Store for the Iphone and Ipod touch, continue to use Apple’s fair play DRM to inhibit casual copying.
Other Online music stores that offer different approaches to DRM are:
Bandwidth Throttling is a method of ensuring a bandwidth intensive device, such as a server, will limit (throttle) the quantity of data.
Decoy Files is a file bearing a title of a song, purposely put through P2P (Peer to Peer) networks, in order to make it more difficult to locate a real version of a song.
Many decoy files lead off into a brief segment of the sound recording before changing to mere noise.
Creative Commons Copyright
Creative Commons (CC) is a non-profit organisation, devoted to expanding the range of creative works available for others to build upon legally and to share.
The organisation has released several copyright-licences known as Creative Commons Licenses for free to the public.
Creative commons was invented to create a more flexible copyright model, and replaces ‘all rights reserved’ with ‘some rights reserved’
Network Neutrality is a principal proposed for user access networks participating in the internet that advocates no restrictions on content, sites or platforms.
The principal states that if a given user pays for a certain level of internet access and another user pays for the same level of access, that the two users should be able to connect to each other at the subscribed level of access.
