Claim One:
1. An apparatus associated with a mobile device, the mobile device having a touchscreen, comprising: a processor; computer memory comprising a data store, and computer program instructions comprising a state machine having a set of states, the computer program instructions operative to restrict access to the mobile device except to a user whose identity has been authenticated using a first authentication scheme, wherein authentication using the first authentication scheme is a first state, the computer program instructions comprising: first program code operative as the mobile device is being used to monitor interactions with the touchscreen against fingerprint data associated with the user whose identity has been authenticated; second program code that determines, within a given threshold, and based on the monitored interactions, whether an individual currently interacting with the mobile device, as represented by the interactions, could be the user whose identity has been authenticated using the first authentication scheme, wherein the first and second program code are operative in a second state, the state machine transitioning from the first state to the second state upon authentication using the first authentication scheme; and third program code that transitions the mobile device to a restricted mode of operation, the restricted mode being a third state, the state machine transitioning from the second state to the third state when it cannot be assured that the individual currently interacting with the mobile device could be the user whose identity has been authenticated; the second program code operative in the second state to continue evaluating the monitored interactions upon a determination that the individual currently interacting with the mobile device could be the user whose identity has been authenticated and until the state machine transitions from the second state to the third state such that the third program code transitions the mobile device to the restricted mode.
