DRM

Digital rights management (DRM) is a technology that controls access to copyrighted material. DRM allows copyright holders and content creators to manage what users can do with their content, such as how many devices they can access media on and whether they can share it.
DRM is designed to protect the rights of the copyright holder and prevent unauthorized modification or distribution. It uses a variety of methods and technologies to accomplish this goal, including restricting or preventing users from editing, saving, sharing, forwarding, or printing content.
