Medical Data Communication Apparatus for Flexible Personal Information Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical data communication technologies face challenges in flexibly protecting personal information, as the range of information to be protected changes with laws, guidelines, and environmental needs, making it difficult to update medical devices for secure external network distribution without risking personal information leakage.
Innovation Solution
A medical data communication apparatus and method that interposes between medical devices and external networks, allowing for flexible modification of personal information through a server-provided instruction, performing data acquisition, modification, and output, ensuring that personal information is protected before distribution, using techniques like mask processing and CG replacement for image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the range of personal information protection is changed according to laws and guidelines, then the protection effectiveness is improved, but the medical device requires re-authentication which reduces productivity
Solution Approach 1:
The system separates the medical device from the data processing function by introducing an external communication device. The medical device generates medical data, while the external communication device performs the modification of personal information based on external instructions. This segmentation allows the medical device to remain unchanged while still achieving flexible protection of personal information.
Solution Approach 2:
An external communication device acts as an intermediary between the medical device and the external network. This intermediary receives modification instructions from external servers and applies them to medical data before transmission, thereby enabling flexible adaptation to changing legal and guideline requirements without modifying the authenticated medical device.
2Reliability
If encryption is applied to the entire medical data file, then the security is improved, but the ability to selectively protect specific personal information is reduced
Solution Approach 1:
Instead of applying uniform encryption to the entire medical data file, the system modifies only specific pieces of personal information within the data based on modification instructions. This local quality approach allows selective protection of specific personal information items while leaving other data intact, providing both security and adaptability.
3Reliability
If medical devices are updated to change specifications for better data protection, then the protection capability is improved, but the authentication requirement increases device complexity
Solution Approach 1:
The data protection functionality is extracted from the medical device and placed in the external communication device. This extraction allows the medical device to maintain its simple authenticated structure while the complex data modification operations are performed externally, avoiding increased device complexity and authentication requirements.
