Title: MOBILE DEVICE AUTHENTICATION USING DIFFERENT CHANNELS
Abstract:
An authentication system (21) is disclosed which is configured, in response to receiving a request to authenticate a transaction, to send a first challenge (313) to a mobile terminal (4) via a first channel (78) and, in response to receiving a first response (316) to the first challenge to determine whether the first response is correct, to send a second challenge to the mobile terminal (4) via a second, different channel (79) and, in response to receiving a second response (338) to the second challenge to determine whether the second response is correct, and, in dependence upon the first and second responses being correct, to signal that the transaction is authenticated.
