Kugou Music adopts digital copyright protection technology, namely digital copyright management (DRM) technology, which is a digital copyright protection measure designed to ensure that music copyright is protected and prevent piracy and illegal dissemination. DRM technology encrypts and authorizes digital content so that users can only use and disseminate digital content under specific authorization conditions. Therefore, when users use the Internet to directly download songs from Kugou Music, they cannot obtain the decryption key of the songs due to lack of authorization, resulting in the inability to download and play these copyright-protected songs.
