SecuROM

SecuROM is a CD/ DVD copy protection and digital rights management (DRM) product developed by Sony DADC. Its purpose is to resist home media duplication devices, professional duplicators, and reverse engineering of software, primarily commercial computer games running under the Microsoft Windows platform. The method of disc protection in current versions is Data Position Measurement; this may or may not be used in conjunction with online DRM components.

Opponents, including the Electronic Frontier Foundation, believe that fair-use rights are restricted by DRM applications such as SecuROM. SecuROM has generated controversy because it is not uninstalled upon removal of the game. A 2008 class-action lawsuit was filed against Electronic Arts for its use of SecuROM in the video game Spore.
