SecuROM

SecuROM is a CD/DVD copy protection and digital rights management (DRM) system developed by Sony DADC. It aims to prevent unauthorised copying and reverse engineering of software, primarily commercial computer games running on Windows. The method of disc protection in later versions is data position measurement, which may be used in conjunction with online activation DRM. SecuROM gained prominence in the late 2000s but generated controversy because of its requirement for frequent online authentication and strict key activation limits. A 2008 class-action lawsuit was filed against Electronic Arts for its use of SecuROM in the video game Spore. Opponents, including the Electronic Frontier Foundation, believe that fair-use rights are restricted by DRM applications such as SecuROM.
