Abstract:
1. A method of controlling access to a data network from a visited access provider, comprising the visited access provider receiving from a client device a message indicative of a request to access the data network; the visited access provider supporting a temporary connection between the client device and a credit provider, the temporary connection comprising a transmission of substitute user credentials from the credit provider in response to transmission of original user credentials from the client device, wherein supporting the temporary connection further comprises redirecting the client device to the credit provider in response to receiving data indicative of the credit provider from the client device; the visited access provider receiving the substitute user credentials from the client device; the visited access provider communicating the substitute user credentials to the credit provider to authenticate the client device; responsive to successful authentication of the client device by the credit provider on the basis of the substitute user credentials, the visited access provider authorizing the client device to access the data network; wherein the temporary connection is secured to prevent the visited access provider from determining the original user credentials transmitted by the client device.
