Iris-Based First-Aid Code Display for Secure Medical Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing first-aid information systems cannot provide information to unconscious or incapacitated individuals and lack protection against unauthorized access when the owner is not present, as they require operation by the owner to function and are vulnerable to information leakage.
Innovation Solution
A first-aid information provision system using an information display device that captures an iris image, acquires and displays a code associated with the image, and an information output device that images and outputs first-aid information using the code, ensuring information is accessible without owner operation and protecting against unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system allows third-party operation of mobile terminals to provide information when the owner cannot operate, then information accessibility is improved, but information security deteriorates due to theft and unauthorized access
Solution Approach 1:
The system performs preliminary authentication by capturing the owner's iris image before allowing information access. This preliminary action ensures that only the authorized owner can retrieve information, preventing unauthorized access while still allowing third parties to operate the device when the owner is incapacitated.
Solution Approach 2:
The system introduces an intermediary authentication mechanism (iris recognition) between the device operation and information provision. This intermediary layer verifies the owner's identity before allowing information access, resolving the contradiction by enabling third-party operation while maintaining security through biometric verification.
2Object-affected harmful factors
If the system requires owner operation to ensure security, then information security is improved, but information accessibility deteriorates for unconscious or incapacitated individuals
Solution Approach 1:
The system uses the owner's own biometric data (iris image) as the authentication key, eliminating the need for the owner to manually operate the device. The device automatically captures and verifies the iris image, allowing information access without requiring the owner's active participation while maintaining security.
Solution Approach 2:
The system replaces the mechanical operation requirement (owner manually operating the device) with an optical recognition system (iris capture and verification). This substitution allows information access for incapacitated individuals while maintaining security through automated biometric authentication.
3Adaptability or versatility
If the system stores detailed medical information, then information utility is improved, but information security risk increases due to sensitivity of medical data
Solution Approach 1:
The system performs preliminary iris-based authentication before providing access to detailed medical information. This preliminary security check ensures that only the authorized owner can access sensitive data, allowing the system to store comprehensive medical information while maintaining security through pre-access verification.
