A SYSTEM AND METHOD OF TRANSFERRING DIGITAL RIGHTS TO A MEDIA PLAYER IN A DRM ENVIRONMENT

摘要

A system is provided in which a DRM service platform (2) is configured to dispense rights objects (RO) to media players (1) that are uniquely identifiable by way of unique identification data (GUID) with the digital media files encrypted into content objects (CO) that require a content object key (COk) in order to decrypt the content thereof and make it available, in real¬ time. The content object key is embodied in a rights object that is in turn transmitted to a particular media player in an encrypted format capable of decryption utilising at least some of the unique identification data of the particular media player and each media player has a processor capable of decrypting content objects in real-time to render the digital media files usable. Computer means (6) are interposed between a DRM service platform and a media player and are configured to share a unique interface key (IK) for communications with each unique media player and to decrypt a rights object received from the DRM service platform to retrieve the content object key contained therein and re-encrypt it with the unique interface key for onward transmission to the particular media player that is enabled to decrypt the content object key utilising its unique interface key.
