USER AUTHENTICATION

摘要

A method of user authentication by an application (1a) on a mobile telephony device (1) comprises authenticating the user by interaction with the application (1a), communicating with a remote authentication service (4) to receive a call identifier; and sending the call identifier within a telephone call to the remote telephony service (9), by means of which the user is authenticated to the remote telephony service (9). The mobile telephony device may receive a service code linked to the remote telephony service, and the call identifier may be based on this code. The service code may be captured or entered manually into the mobile device, or obtained from an application on the mobile device (1), such as a mobile banking application. The call identifier may be hidden within the call using audio steganography. The authentication service (4) may link the user to a remote service account ID, which is sent to the remote server.
