electronic media management system (copy protection) (EMMS)

Electronic Media Management System(EMMS) is an IBM copy protection method that can be used to copy-protect audio file formats. The EMMS system watermarks and copy-protects any audio file format.

EMMS was initially limited exclusively to copy protection of music files, in which it ensures, similar to the country code in DVDs, that a particular piece of music can only be played in certain regional areas. In addition, plug-ins for RealJukebox and Music Match Jukebox are intended to enable payment for licenses.

As EMMS was not to be limited to music files over time, it was also applied to other file formats for lyrics and videos.

Therefore, the second version of EMMS offers the possibility to protect other streaming files such as video, graphics and texts from unauthorized copying. In this version, a comprehensive rights assignment regarding the frequency of playing and copying is included.
