I was musing in the Muse under some yews outside SMU's museum, as I'm used to doing, when a kitten's musical mews drew me into the museum's mews, which some use -- damn youse -- to sniff mucilage for amusement.

examples of DRM (removed from digital rights management)

DRM systems and implementations

Examples of existing "digital rights management" and "copy protection" systems:

   * Adobe Systems .PDF can restrict document printing: "... a publisher might give users the ability to print several pages of a cookbook within a set period of time."
   * Advanced Access Content System (AACS) used by Blu-ray and HD-DVD high capacity optical disk proposals; mandatory that disk drives incorporate firmware implementing this scheme. Reduces resolution over non-encrypted interfaces to 960 x 540 pixels. If a display device doesn't meet the Intel HDCP specification, HD resolution, even when already paid for, will not be permitted.
   * Agilis Software license management solutions.
   * Authena Open Source DRM
   * Authentica is part of EMC Corporation. They provide "Secure Mail," "Secure Mobile Mail" and "Secure Documents" products, primarily for Microsoft Office and Portable Document Format (PDF) files.
   * AXMEDIS which is an architecture supporting DRM based on MPEG-21 and ODRL.
   * BD+ a method of updating copy protection keys should they be cracked, specified in the Blu-ray proposal. Similar in concept to a certificate revocation list.
   * Content Protection for Recordable Media (CPRM) used in Secure Digital cards
   * Content Protection for Prerecorded Media (CPPM) used in DVD-Audio
   * CoreMedia AG combining OMA DRM and WMDRM, implemented at 30 operators and handset providers on 5 continents, approved by all music majors and hollywood studios.
   * CryptoCell embedded security package for OMTP cellular handsets by Discretix. The DMR component is provided as software, while the rest of the product is hardware based.
   * Digital Transmission Content Protection (DTCP)
   * High-Bandwidth Digital Content Protection (HDCP) from Intel and used in, for instance, HD-DVD and Blu-ray optical disk proposals.
   * iTunes (which incorporates Apple's FairPlay DRM for content downloaded through the iTunes Music Store).
   * Key2Audio used by Sony BMG
   * Macrovision
   * MediaMax CD-3 used by Sony BMG
   * Mandatory Managed Copy system MMC Blu-ray proposal technique permitting a small number of secure copies of a protected optical disk for personal use; will require registration with content provider to obtain needed keys
   * OMA DRM specifications developed by the Open Mobile Alliance
   * RealNetworks Music Store from RealNetworks have their own DRM scheme named Helix DRM
   * ROM-Mark a digital watermark scheme for factory produced Blu-ray optical disk content which is intended to prevent untraceable copying of those Blu-ray disks.
   * SealedMedia. DRM applied to securing and tracking sensitive documents and emails for enterprises and government agencies.
   * Serial copy management system (SCMS)
   * Sony has announced their own DRM protected music store named Connect, using their DRM technology OpenMG. OpenMG supports the Sony ATRAC sound format.
   * Sony/BMG included two kinds of DRM software in many titles (in millions of copies) of music CDs released ending in 2005. One, from a British firm, installed a rootkit on customer computers which was exploited by several viruses not long after it became public. Sony is currently being sued in several US states and by the EFF, and is the subject of multiple boycott proposals as a result.
   * Steam used by Valve Software to digitally distribute, manage, authenticate and auto-update games such as Half-Life 2 and Counter-Strike: Source.*
   * Windows Media DRM (WMDRM) which protects Windows Media Audio or Windows Media Video content and is implemented in Windows Media Player
   * Windows Rights Management Services is a component for Windows that lets companies apply DRM restrictions to documents, such as protecting them from being copied, printed, or emailed.
   * XCP / Extended Copy Protection used by Sony BMG
