ABSTRACT:
A wireless terminal implements location-based transaction authentication and includes a wireless interface, a user interface, a Global Positioning System (GPS) receiver, and a processing unit. The wireless terminal receives a transaction request from the user, accesses a servicing network via the wireless interface, sends a transaction initiation request to the servicing network, receives an authentication challenge from the servicing network, and determines its current location via access of the GPS receiver. The wireless terminal prepares and transmits an authentication response based upon the received location. When the authentication response is accepted by the servicing network, the processing unit is able to service the transaction between the user and the servicing network. When the authentication response is rejected the transaction is not serviced. Relative location information and further user authentication may also be used.
