Abstract

We describe an electronic document reading device comprising: a wireless remote content connection; a physical user interface for receiving device control commands from a user; non-volatile data storage; a non-volatile electrophoretic display screen; and a device controller. The controller has program code to: read an item of electronic document content from said non-volatile data store; wherein the item of electronic document content includes: i) electronic document content display data, ii) a location based permission control object configured to define allowed location-based display of the content display data on the electrophoretic display; determine a physical location of the reading device; and operate with the permission control object to determine whether display of the content display data is permitted at the physical location, wherein operating with the permission control object enables the item of electronic document content to control whether its own content is displayed on the non-volatile electrophoretic display screen.
