About summary of the indicator system in COVSAFE solution

• The summary of indicator system in COVSAFE solution is following.
  • COVSAFE Risk Calculator/Notifier triggers the indivisual risk state change and sends a push notification to the indivisual's mobile device via the Push Notifications service. These sequences are performed by Cloud Functions configured as a COVSAFE backend. Here, the backend uses the device ID as an identifier to identify the indivisual to whom push notifications are sent; the COVSAFE mobile app stores the device ID in the backend cloudant in association with the logged-in App ID user. The back-end COVSAFE risk notifier identifies the destination of the pusho notofications by referring to the DB information in this cloudant.
  • COVSAFE mobile app executes an IFTTT incoming webhook by the notification handler when it receives a push notification, and then the corresponding MESH app script is executed. and changes the color of the MESH LED (LED indicator device) paired with the BLE.
