wherein the processor sends a further communication to the entity indicating if the transaction is authorized; and
wherein determination if the communication response to the first reply address authorizes the transaction includes verifying correspondence of both the mobile device's address and the first reply address of the communication response with the mobile device's address and the first reply address of the sent communication.

causing the generated communication to be sent from a reply address to the retrieved mobile device address, wherein the reply address is selected from a plurality of available reply addresses prior to sending the generated message;
determining whether a reply communication received at the reply address from the mobile device address authorizes the transaction, wherein determination if the reply communication received at the reply address authorizes the transaction includes verifying correspondence of both the mobile device's address and the reply address of the reply communication with the mobile device's address and the reply address of the sent communication; and
sending a response communication to the authorization request in response to a determination that the transaction is authorized.
8. The mediator of claim 7 , wherein the mediator is coupled to telecommunications networks and wherein the request for transaction authorization and the reply communication is received from the user's mobile device via at least one of the one or more telecommunications networks.
