Abstract

A communications system includes a plurality of recipient processors located at geographically remote locations with respect to each other and connected for communication with an information provider processor, over the communications network. The provider and recipient processors may comprise respective computers coupled for communication on the internet or world-wide-web. The provider processor is capable of providing information from any suitable source, by communicating such information over a communications network. However, access to the information by the recipient processors is controlled, based on the geographic location or region of the recipient processors. Each recipient processor is operably associated with a positioning system for providing geographic location information corresponding to the location or region in which the positioning system is located, such as a global positioning system GPS. The geographic position information is used to determine whether or not the processor requesting the information is within a restricted (or limited) or non-restricted region. This determination may be made comparing the geographic information provided by the recipient processor and positioning system with a list of non-restricted or non-limited (or restricted) geographic locations or regions.
