Abstract: Systems, techniques, and devices for performing variable power transmission for a battery-powered device are disclosed. In certain embodiments, the techniques include determining a proximity of the transmitter to a first display device. An output transmission power of the transmitter is determined based on the proximity. Analyte information from an analyte sensor coupled to the transmitter is transmitted to the first display device at the output transmission power.

Abstract: Systems, techniques, and devices for performing passive continuous authentication of a user of display device are disclosed. In certain embodiments, the techniques include obtaining first information including at least one of (i) non-analyte sensor data from one or more sensors of a display device or (ii) analyte sensor data from an analyte sensor system. The techniques further include authenticating an identity of the user of the display device at a first point in time and based on the first information. The techniques further include allowing the user of the display device to access a medical device software running on the display device without prompting the user for authentication information, upon determining that the authentication at the first point in time is successful.

Abstract: Techniques for performing application-layer security and communication over primary invitation channels are disclosed. In certain embodiments, analyte data is obtained from an analyte sensor electrically coupled to a sensor electronics module of an analyte sensor system. A secret key is established with a display device over one or more primary invitation channels. The analyte data is encrypted using the secret key. The encrypted analyte data is broadcast over the one or more primary invitation channels.

Abstract: Methods and apparatus are provided for securely obtaining access to patient data associated with a patient using a sensor system configured for monitoring analyte levels of a patient. In one aspect, a method includes receiving, at a display device, one or more communications from the sensor system, wherein the one or more communications include identifiable information associated with the sensor system and are transmitted by the sensor system via an advertisement channel; inserting, at the display device, the identifiable information in a web request; providing, at the display device, the web request including the identifiable information to a data management system to request access to the patient data; and obtaining access to the patient data through a web browser upon the data management system verifying that the identifiable information matches a second identifiable information stored in the patient data.
