Systems, devices, and methods for authentication in an analyte monitoring environment

Abstract

Systems, devices, and methods are provided that allow the authentication of devices within analyte monitoring systems. The analyte monitoring systems can be in vivo systems and can include a sensor control device with a sensor and accompanying circuitry, as well as a reader device for communicating with the sensor control device. The analyte monitoring systems can interface with a trusted computer system located at a remote site. Numerous techniques of authentication are disclosed that can enable the detection of counterfeit components, such as a counterfeit sensor control device.

         21 . An in vivo analyte monitoring system, comprising a reader device and sensor control device,
 wherein the sensor control device comprises a sensor and analyte monitoring circuitry, and the sensor is adapted to be inserted into the body of a user;   wherein the reader device is configured to:
 send an identification request to the sensor control device via a local wireless communication path; 
 receive from the sensor control device, in response to the identification request, an identifier and a token via the local wireless communication path; 
 authenticating the sensor control device based on the identifier and token obtained from the sensor control device; 
 and if the sensor control device is authenticated, reading sensed analyte data from the sensor control device. 
   
     
     
         22 . The system of  claim 21 , wherein the reader device is configured to communicate with the sensor control device over the local wireless communication path using: a Near Field Communication, NFC, protocol; a Radio Frequency Identification, RFID, protocol; a Bluetooth protocol; or a Bluetooth Low Energy protocol. 
     
     
         23 . The system of  claim 21 , wherein the reader device is a smart phone, a tablet, a smart glass, or a smart glasses. 
     
     
         24 . The system of  claim 21 , wherein the reader device is further configured to,
 if the reader device determines that the sensor control device is authentic and if the sensor has been inserted into the body of the user, then to read information indicative of an analyte level of the user from the sensor control device and display the analyte level on a display of the reader device; and   optionally if the reader device determines that the sensor control device is not authentic, terminate operation of the reader device with the sensor control device.   
     
     
         25 . The system of  claim 21 , wherein the reader device is configured to use a remote trusted computer system to verify authenticity of token and identifier. 
     
     
         26 . The system of  claim 21 , wherein the reader device is configured to store tokens and identifiers on a local registration database and to perform verification of the authenticity of the token and the identifier.
