摘要

A method for managing users' digital rights to documents protected by digital rights management (DRM), comprising the steps of a rights management system (RMS) server receiving a request from a user for accessing a DRM-protected document, and the RMS server executing a user centric adaptor (UCA) module to check in a UCA database under the user's identification (ID) whether one of a limited number of predetermined policies of digital rights is added to the user's ID, whereas if the user's rights to the document is not revoked by deletion of a predetermined policy under the user's ID in the UCA database, then the UCA module does not block granting the user's request.
