The main function of a digital rights management (DRM) system is to protect and manage the copyrights of digital media and intellectual property. DRM technologies control how digital content is used, distributed, and accessed, thereby preventing unauthorized copying, sharing, or piracy. It employs encryption and licensing technologies to restrict user access and ensure that content is consumed according to the terms set by the rights holder. This helps creators and businesses safeguard their revenue streams in an increasingly digital landscape.
