TECHNIQUE FOR SECURE NETWORK TRANSACTIONS

摘要

A system for performing regulated transactions is used with a network (104) that is commonly accessible by a plurality of communication terminals (102). A gatekeeper (108), coupled to the network (104), permits access to the system only if authorization information, as indicated by an authorization signal received by the gatekeeper (108) from a communication terminal via the network (104), complies with at least one predetermined criterion. The authorization information includes information independent of information supplied by a communication terminal user and independent of information indicative of a communication line coupled to the user's communication terminal. A host (110), coupled to the gatekeeper (108), receives a first signal from the user's communication terminal through the network (104) and sends a second signal through the network to the user's communication terminal in response to the first signal.
