The primary characteristic of a digital rights management (DRM) system is its ability to control how digital content is used and distributed. DRM technologies aim to prevent unauthorized access and copying of copyrighted materials like music, movies, and software. By implementing encryption and access restrictions, DRM ensures that creators and distributors retain control over their products and can profit from their work. Although DRM can protect intellectual property, it is often criticized for limiting consumer freedom and creating issues related to access and usability.
