Description

technical field [0001] The invention relates to the field of digital rights management (DRM), in particular to a method, device and system for realizing non-consumable domain license transfer. Background technique [0002] Digital Rights Management (DRM) mainly controls the use of digital content through rights restriction and content protection schemes, and protects the legitimate rights and interests of content owners. After the digital content issuer (Content Issuer, CI) encrypts the digital content, the user downloads the encrypted digital content data package to the terminal device; the authorized issuer (Rights Issuer, RI) is responsible for distributing the license corresponding to the digital content , including the content decryption key and corresponding permissions. The purchased digital content can only be used normally by the terminal device only if it has both the content data package (which contains the information necessary for decrypting the digital content...
