Biometric Measurement System Secure Pairing via Notification Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems for biological information, such as blood glucose levels, face security challenges when transmitting measurement results between a measurement device and a terminal device, especially when the measurement device lacks a display to convey pairing codes.
Innovation Solution
A measurement system that includes a measurement device with dual communication units, a terminal device for wireless communication, and a notification device for wired communication, where higher security communication is ensured between the measurement device and the terminal device when the measurement device is connected to the notification device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the measurement device does not include a display to improve portability, then portability is improved, but security deteriorates because the user cannot see the passcode for pairing
Solution Approach 1:
The patent introduces a notification device as an intermediary component that displays the passcode generated by the measurement device. This mediator allows the user to view the passcode without requiring a display on the measurement device itself, thus maintaining portability while enabling secure pairing through visual confirmation of the passcode
2Ease of operation
If the measurement device communicates with any terminal device without pairing, then ease of operation is improved, but security deteriorates because unauthorized devices can access measurement results
Solution Approach 1:
The patent implements pairing as a preliminary action that must be completed before communication between the measurement device and terminal device can occur. The passcode displayed on the notification device enables the user to authenticate the terminal device in advance, ensuring that only authorized devices can subsequently access measurement results

AI summary
A measurement system includes: a measurement device that includes a first communication unit performing communication by a first communication method and a second communication unit performing communication by a second communication method different from the first communication method and that acquires a measurement result of biological information of a user; a terminal device that includes a terminal communication unit that performs communication with the first communication unit of the measurement device; and a notification device that includes a notification communication unit that performs communication with the second communication unit of the measurement device by the second communication method, and a notification unit that notifies of information. Higher security communication is performed between the measurement device and the terminal device in a case in which the measurement device is in communication with the notification device than in a case in which the measurement device is not in communication with the notification device.
