Wearable Device Biometric Data Provisioning for Medical Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face challenges in securely and promptly providing biological data to medical professionals, especially in emergency situations where the device wearer is unconscious and cannot grant permission.
Innovation Solution
A wearable device with a processor that collects and stores biological data, includes prior approval settings for data output, and automatically provides approved data to medical devices based on stored approval information and medical device information, including features like biometric authentication and expiration dates for approval settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior approval is obtained for data provision, then data security and authorization are ensured, but data provision becomes time-consuming and cannot be performed in emergency situations
Solution Approach 1:
The system performs preliminary actions by obtaining user approval in advance through biometric authentication and storing it as approval information. This pre-approved data can then be quickly provided to medical devices in emergency situations without requiring real-time user consent, thus resolving the contradiction between security and speed.
2Reliability
If real-time approval is required for data provision, then user consent is ensured, but data provision becomes impossible when wearer is unconscious
Solution Approach 1:
The system performs preliminary action by obtaining and storing user approval information in advance through biometric authentication. When the wearer is unconscious or unable to provide consent, the pre-stored approval information enables automatic data provision to medical devices, ensuring both user consent and operational capability.
3Measurement precision
If detailed approval settings are implemented for each measurement item, then data authorization precision is improved, but system complexity increases
Solution Approach 1:
The system segments the approval process by creating separate approval information records for different measurement items (e.g., heart rate, blood pressure, oxygen saturation). This allows precise control over which specific data types can be shared, while the automated biometric authentication system manages the complexity of obtaining and storing multiple approvals.
Data Source
AI summary
A smart watch which is a wearable device collects data while worn including at least biological information of a wearer in a healthy state, stores approval information for controlling output of the data while worn by prior approval of the wearer, receives a data provision request for a medical device that generates medical diagnostic information, and provides the data while worn to the medical device based on the approval information and the data provision request. A doctor makes a medical diagnosis using the data while worn acquired by the medical device and examination data.
