Abstract
In a digital rights management system, a rights management server sends event notifications to certain users when other users perform certain actions (read, print, copy, etc.) on documents managed by the system. For each document, a notification rule defines which users will receive what event notifications for that document. The notification rule is determined based on document access permissions possessed by the users, so that only users who have permission to perform an action on the document will receive notifications when other users perform that action on the document, while users with no permission to perform an action will not receive notifications when other users perform that action. The server also allows the users who have permission to perform an action to opt out of the notifications. The server monitors events that occur on the documents, and sends event notifications to appropriate users according to the notification rules.
