ABSTRACT:
Information rights management (IRM) systems enable information to be protected after it has been accessed by or delivered to an authorized individual. For example, this might be to allow an email to be viewed for a limited time by specified individuals but to prevent that email from being forwarded. However, existing IRM systems are limited in the situations in which they may operate. An IRM server is provided which communicates with one or more policy evaluators which are independent of the IRM server. Results from the different policy evaluators may be combined by the IRM server and one or more identity providers may be used in conjunction with each policy evaluator. By enabling the IRM server to act as a broker between authors, recipients and policy evaluators situations in which IRM systems may operate are greatly extended.
