Biological Data Relay Device Segmentation for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological information management systems face security risks such as information leaks, unauthorized viewing, and tampering, particularly outside emergency situations, due to inadequate protection of sensitive personal and medical information.
Innovation Solution
A biological information management system that transmits and stores time-series waveform data from biological sensors without attaching user IDs, using sensor IDs instead, to prevent the generation of medical information and maintain data security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If user ID is attached to time-series waveform data for identification purposes, then data traceability is improved, but information security deteriorates due to risks of information leaks and unauthorized viewing
Solution Approach 1:
The patent segments the identification function from the data itself by using separate sensor-related IDs for waveform data and user-related IDs for biological information, preventing direct association and enhancing security while maintaining traceability
Solution Approach 2:
The patent introduces an intermediary mechanism where the server acts as a mediator that receives sensor-related IDs from the relay device, stores them separately from user identities, and enables traceability without exposing sensitive personal information
2Adaptability or versatility
If time-series waveform data is processed into biological information in relay or server devices, then data utility is improved, but information security deteriorates due to generation of sensitive personal information
Solution Approach 1:
The patent divides the data processing function into separate stages: the biological information sensor performs the actual processing of time-series waveform data into biological information, while the relay device and server only handle unprocessed data and IDs, preventing unauthorized generation of sensitive information
Solution Approach 2:
The biological information sensor is equipped with the capability to process time-series waveform data into biological information independently, eliminating the need for relay or server devices to perform processing that would generate sensitive personal information
Data Source
AI summary
A biological information management system is provided with enhanced security. The biological information management system includes a biological information sensor that measures time-series waveform data of an electric signal related to biological information of a user and transmits the measured time-series waveform data of the electric signal and a sensor ID. The system further includes a relay device that transmits the time-series waveform data of the electric signal and a sensor-related ID related to the sensor ID without attaching a user ID, which is personal information, to the time-series waveform data of the electric signal and the sensor-related ID. A server device stores the time-series waveform data of the electric signal and the sensor-related ID received from the relay device without attaching the user ID, which is the personal information, to the time-series waveform data of the electric signal and the sensor-related ID.
