Wearable Device Dynamic Access Control for Medical Records
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for secure and efficient sharing of electronic medical records between medical institutions while preventing unauthorized data changes, especially when the user is not present in the institution.
Innovation Solution
A wearable electronic device with communication circuitry that authenticates users and medical workers, allowing read access to vital sign and medical information databases while preventing write access when the user is not present, using a near-field communication terminal and cloud servers to manage access rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic medical records are shared with medical institutions, then accessibility and collaboration are improved, but data security and unauthorized modification risks worsen
Solution Approach 1:
The patent implements dynamic access rights that automatically change based on the user's presence status. The system transitions between different access modes (read-only when absent, read-write when present) based on real-time detection of user presence at the medical institution, resolving the contradiction between accessibility and security.
Solution Approach 2:
The system uses feedback from presence detection mechanisms (such as terminal device detection, clock-in/clock-out systems) to automatically adjust access permissions. This closed-loop control ensures that security measures are dynamically applied based on actual user presence, balancing accessibility needs with security requirements.
2Productivity
If write access is always granted to medical institutions, then efficiency of record updating is improved, but risk of unauthorized changes when user is absent worsens
Solution Approach 1:
The patent implements conditional access rights that dynamically switch between read-only and read-write modes based on user presence. When the user is detected as present at the medical institution, full write access is granted for efficient record updating. When absent, the system automatically restricts access to read-only mode, preventing unauthorized changes while maintaining operational efficiency when appropriate.
Solution Approach 2:
The system performs preliminary presence verification before granting write access. By detecting user presence in advance through terminal devices or clock-in systems, the system proactively configures appropriate access levels, ensuring that write operations are only permitted when the user is actually present, thus preventing unauthorized changes before they can occur.
3Reliability
If access rights are restricted when user is absent, then data security is improved, but operational efficiency during legitimate updates worsens
Solution Approach 1:
The patent implements dynamic access control that automatically adjusts permissions based on real-time presence detection. The system transitions between restricted (read-only) and permissive (read-write) modes seamlessly, ensuring data integrity when users are absent while maintaining operational efficiency when they are present and legitimate updates are needed.
Solution Approach 2:
The system performs automatic presence detection and access right adjustment without requiring manual intervention. The electronic device or medical institution terminal automatically detects user presence through clock-in/clock-out mechanisms or terminal device identification, and the system self-adjusts access permissions accordingly, eliminating the need for manual security management while maintaining both security and efficiency.
