Biometric Sensor Module Validity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous biometric information measuring devices, such as those used for diabetes management, face challenges in preventing the use of expired or defective sensor modules, which can lead to inaccurate measurements and health risks due to reuse or shared use.
Innovation Solution
A method is introduced to manage biometric information by determining the validity of sensor modules based on identifier, manufacturing date, or production lot information, and preventing reuse or shared use by comparing user information in measurement messages with registered user information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor module expiration management is not implemented, then device complexity is reduced, but reliability deteriorates due to use of expired or defective sensors
Solution Approach 1:
The system performs preliminary validation of sensor modules by checking expiration dates and defect information before the sensor is used for measurement. The server stores expiration dates and defect information in advance, and the user terminal checks these parameters before allowing sensor module operation, preventing use of invalid sensors proactively
Solution Approach 2:
The system establishes a feedback loop where the user terminal communicates with the server to obtain real-time validity status of sensor modules. The server provides feedback on expiration dates and defect information, and the user terminal uses this feedback to control whether the sensor module can be activated or used for measurements
2Productivity
If sensor module reuse is allowed, then productivity increases, but harmful factors increase due to infection risks
Solution Approach 1:
The system treats sensor modules as disposable items with limited validity periods. Each sensor module has an expiration date stored on the server, and after expiration or upon detecting defect information, the system automatically prevents further use. This approach prioritizes safety over reusability, ensuring that each sensor module is used only within its valid lifecycle
Solution Approach 2:
The system performs preliminary checks for defect information and expiration status before allowing sensor module activation. By checking these parameters in advance against the server database, the system prevents potential infection risks from reused or expired sensors before they can affect users
3Reliability
If user information verification is not performed, then ease of operation improves, but reliability deteriorates due to shared use of sensors
Solution Approach 1:
The system implements a feedback mechanism where user information is verified against the server database before sensor activation. The server provides feedback on whether the sensor module is already associated with another user or has defect information, and the user terminal uses this feedback to either allow or block sensor activation, ensuring user-specific measurement accuracy

AI summary
The present invention relates to a method for managing biometric information and, more specifically, to a method for managing biometric information capable of preventing a use of a sensor module of which an expiration date has expired or a defective sensor module, by determining the validity of a sensor module of a continuous biometric information measuring device on the basis of the generation date of sensor usage information or production lot information received from the continuous biometric information measuring device, and preventing re-use or shared use of the sensor module on the basis of user information provided in a measurement message received from the continuous biometric information measuring device.
