Digital Rights Management
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures, such as access control technologies, can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification and distribution of copyrighted works (e.g. software, multimedia content) and of systems that enforce these policies within devices. DRM technologies include licensing agreements and encryption. Laws in many countries criminalize the circumvention of DRM, communication about such circumvention, and the creation and distribution of tools used for such circumvention. Such laws are part of the United States' Digital Millennium Copyright Act (DMCA), and the European Union's Information Society Directive – with the French DADVSI an example of a member state of the European Union implementing that directive. Copyright holders argue that DRM technologies are necessary to protect intellectual proper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
