AUTHORIZED DOMAIN MANAGEMENT WITH ENHANCED FLEXIBILITY

In Authorized Domains the management of which devices that can access content is a key issue. The Authorized Domain must be limited to a relatively small group of devices to get a solution that is acceptable to both content providers and users. However, current solutions are typically either to rigid to be future proof and user friendly or not effective enough in limiting the size of the Authorized Domain. This invention provides a user-friendly, flexible and yet effective method of managing the size of an Authorized Domain. The method proposes to group devices in the Authorized Domain into clusters, if a predetermined requirement is met, and to limit the number of clusters. Such a predetermined requirement could be a proximity requirement.
