Digital rights management

Digital Rights Management (DRM) is a way for companies to protect their digital products (like books, music, and movies) from being copied or shared without permission. It can also be used to prevent people from changing the product, like editing or remixing it. It works by putting special software code onto digital products that only allow certain types of uses. For example, if you buy a movie, you might only be allowed to view it on a certain device or web browser – but not copy it or save it to your computer. This is how companies make sure that people buy their products instead of getting them for free.
