The function of digital rights management (DRM) is to protect copyrighted content by controlling access and usage of digital media. DRM technologies help copyright holders manage how their works are distributed and consumed across various platforms. By implementing DRM, creators can impose restrictions on copying, sharing, and viewing their content, ensuring that they receive appropriate compensation for their work. DRM is commonly used in industries such as music, film, and eBooks, but it has also faced criticism for limiting consumer rights and the usability of purchased content.
