retrieving a pre-stored signature image for the user in response to the authenticating.

11. The non-transitory computer-readable medium of claim 10 , wherein the determining is further based on a pre-determined time window for authentication.

12. The non-transitory computer-readable medium of claim 7 , wherein generating the fax document comprises:
