Abstract: A display interface at a sending terminal including the conventional means enabling the sender of an electronic mail document to specify recipients to receive the document, but, in addition, provides means enabling the forwarder of the electronic mail document to determine whether a recipient has previously received the electronic mail document. An inventory of duplicate mail recipients is provided to the forwarder of the document in the form of a hidden list of recipients who have previously received the E-mail document. This hidden list is updated as the document is forwarded. The forwarder can select to forward the duplicate mail or discard the duplicate mail automatically. This invention also allows the forwarder of the E-mail document to remove recipients from a distribution list who have previously received the document.

Abstract: A method and system that enables cross-border compliance with export restrictions of particular computer technology, including software loaded on a computing device. The computing device is loaded with software, and has a country location device, such as a low-end GPS device. The country location device (country locator) stores the present geographic location of the device in a location register. When the computing device is turned on or the software is activated for operation on the computing device, a security utility of the software compares the value in the register against a list of pre-established locations that are export-restricted. When the value matches (or falls within a range) of one of pre-established locations, the features of the software that are export restricted are automatically disabled.
