Distributed Medical Record Encryption and Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The widespread sharing of electronic medical records is hindered by the high cost of building and maintaining a system for managing electronic medical records, and there is a risk of data loss in the event of a disaster due to the centralized nature of existing medical record systems.
Innovation Solution
A method and system for distributing and managing medical information on a communication network that involves encrypting and decrypting medical information across multiple computers, using a second computer to acquire, update, and send encrypted data to a plurality of first computers, ensuring data integrity and redundancy through a distributed network architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized system for managing electronic medical records is built, then data management capability is improved, but system cost increases significantly
Solution Approach 1:
The patent divides the centralized medical record management system into multiple distributed nodes (first computers, second computers, third computers) across the network. Each node independently stores and manages copies of medical records, eliminating the need for a single expensive centralized database system while maintaining data management capabilities.
Solution Approach 2:
The patent creates multiple copies of medical records across different computers in the network. The first computers, second computers, and third computers all hold identical or equivalent copies of encrypted medical records, allowing any node to access and manage data without requiring a centralized expensive database infrastructure.
2Device complexity
If medical records are stored in a centralized system, then data management is simplified, but disaster risk increases
Solution Approach 1:
The patent segments the storage location of medical records across multiple geographically distributed computers rather than concentrating them in a single centralized database. This distribution ensures that if one location suffers a disaster, other locations retain copies of the records, providing disaster resistance.
Solution Approach 2:
Each computer in the network (first, second, and third computers) maintains local encrypted copies of medical records with the same security and management capabilities. This local quality ensures that data integrity and availability are preserved at each node, providing redundancy against local disasters.
3Reliability
If encrypted medical information is distributed across multiple computers, then data security is improved, but data access complexity increases
Solution Approach 1:
The patent distributes identical encrypted copies of medical records across multiple computers (first, second, and third computers). Since each node holds the same encrypted data, any authorized computer can access and decrypt the records without complex key management or centralized authorization, simplifying access while maintaining security.
Solution Approach 2:
The patent ensures that all computers in the network use the same encryption method and data format for storing medical records. This homogeneity means that any computer can process and access the data using the same protocols, reducing access complexity despite the distributed architecture.
Data Source
AI summary
A method distributes and manages medical information on a communication network over a wide area. Encrypted medical information is acquired from one of a plurality of first computers by a second computer connected to the communication network, the plurality of first computers being connected to the communication network, holding identical medical information, encrypting medical information, and sending and receiving encrypted medical information. The second computer decrypts the acquired encrypted medical information, browses and updates decrypted medical information, and then encrypts the browsed and updated medical information. The second computer then sends the encrypted browsed and updated medical information to the plurality of first computers.
