Claim:
A method of generating an Authorized Domain (AD), the method comprising: selecting a domain identifier uniquely identifying the Authorized Domain; directly binding at least one user to the domain identifier; obtaining a number of devices and a number of users that are authorized to access a content item of said Authorized Domain, wherein the obtaining step comprises: binding at least one device to a plurality of users that includes the at least one user, such that the at least one device is directly linked to the at least one user and is indirectly linked to the domain identifier through the at least one user, by obtaining or generating a Device Owner List for each device to be bound, the Device Owner List comprising a unique identifier for the device to be bound and unique identifiers for the plurality of users, thereby defining that the device is directly bound to the at least one user, and the Device Owner List implemented as or included in a Device Owner Certificate issued by a domain authority of the Authorized Domain; and allowing access to the content item by a given user and/or other users operating a given device that are not directly linked to the content item if the given user and a user to which the content item is linked belong to the same Authorized Domain.
