DIGITAL CONTENT PUBLISHING FOR LIMITING CONTENT RENDERING/USE WITHIN DEFINED GROUP SUCH AS UNIVERSE BASED ON DRM SYSTEM

摘要

PURPOSE: Digital content publishing for limiting content rendering/use within a defined group such as an universe based on a DRM(Digital Right Management) system is provided to allow/facilitate controlled rendering within an office or the universe sharing a document with individuals of the defined universe or a class. CONSTITUTION: A licenser(1210) receives a request including right data associated with contents from a requestor. The right data lists at least one ID(1204) and corresponding rights. The rights describe the issued license(1208). The licenser selects the ID and an associated right set and selects a replacement right set based on the ID. The replacement right set replaces the right set of the right data. As the license is issued to the requestor by using the replacement right set, the replacement right set of the issued license describes terms and conditions kept by the requestor when the matched contents are rendered.
