Method and apparatus for a publish-subscribe system with access controls

摘要

Methods and apparatus are disclosed for notifying one or more users of information. A list of one or more subscribable objects is provided to one or more of the users; a subscription request is received from one or more of the users based on at least one of the subscribable objects; and a determination is made as to whether a user providing a subscription request has a privilege to subscribe to the subscribable object. The list optionally comprises only subscribable objects that the user is privileged to subscribe to. Once one or more users are identified that entered a subscription that matches the notification information, a determination is made as to whether the identified users have appropriate privileges associated with the information before a notification containing the information is sent to the identified users. The appropriate privileges comprise, for example, a privilege to subscribe to an object associated with the information and a privilege to notify any subscribers and delegates associated with the notification.
