Fingerprint enhanced authentication for medical devices in wireless networks
First Claim
1. An infusion system to administer fluid, the infusion system comprising:
- an infusion pump having a pump processor, a pump memory and a pump radio to enable bi-directional communication, the pump radio further including an attenuator being configurable and the pump memory storing a plurality of user-selectable security modes, each of the plurality of user-selectable security modes configuring the attenuator to receive signals of a predetermined strength, anda controller having a controller processor, a controller memory, a controller radio to transmit and receive communication from the pump radio, the controller further having a graphical user interface shown on a display, and controls to manipulate the graphical user interface, the controller being paired with the infusion pump during a pairing phase via fingerprint authentication,wherein after the controller is paired with the infusion pump, and a user selects a security mode, the user-selected security mode is used to configure the attenuator for the bi-directional communication such that both the infusion pump and the controller transmit and expect to receive signals having a signal strength within a specified range for the user-selected security mode, wherein a security check is performed when the infusion pump receives a suspect signal, the suspect signal not matching the predetermined strength associated with the user-selected security mode, wherein the security check further comprises requesting a user to provide a fingerprint, re-calculating tokens associated with the requested fingerprint, sending the re-calculated tokens to the infusion pump, wherein the infusion pump compares the re-calculated token to the fingerprint authentication obtained during the pairing phase, and determining whether the re-calculated token matches the fingerprint authentication obtained during the pairing phase to verify secure communication.

Abstract
An infusion system to administer fluid is disclosed. The infusion system includes an infusion pump having a pump processor, a pump memory and a pump radio to enable bi-directional communication. The pump memory stores a plurality of fingerprint tokens and security conditions. The infusion system includes a controller with a processor, a controller memory and a controller radio to transmit and receive communication from the pump radio. The controller includes a fingerprint scanner and a graphical user interface (GUI) and controls to manipulate the GUI. The GUI and fingerprint scanner enable the controller to scan and determine tokens based on scanned fingerprints. Additionally, communication between the infusion pump and the controller establish relative proximity between the infusion pump and the controller such that when the relative proximity exceeds a threshold distance at least one of the plurality of security conditions is automatically matched.
