Copy protection is a term that refers to the measures put in place to prevent unauthorized copying or distribution of digital content such as software, music, or movies. There are several synonyms for the word "copy protection", including digital rights management (DRM), anti-piracy measures, content protection, copy control, and piracy prevention. These terms are often used interchangeably and describe the same concept of protecting intellectual property. While copy protection measures are essential for content creators to protect their work from piracy and unauthorized distribution, it remains a controversial topic as some consumers view the restrictions as limiting their freedom to use the content they pay for.
