Abstract: Disclosed herein are a method and device for transmitting digital content. A selection of at least one device authorized to receive digital content is detected. It is identified whether each selected device contains a session key that corresponds to a local session key. Digital content is transmitted to each device whose session key corresponds to the local key. Digital content is prevented from transmission to unselected devices not having a corresponding session key.
