Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for recruiting clinical trial volunteers face challenges such as regional limitations, inconvenience in the recruitment process, and inadequate filtering of duplicate volunteers, while also risking personal information leakage during medical data management.
Innovation Solution
A system and method utilizing a distributed key management system with user and hospital agents, encrypting medical data, and storing it on a blockchain for enhanced personal information protection, allowing secure and efficient recruitment and data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If medical data is stored in a centralized database for easy access, then data accessibility is improved, but personal information security deteriorates
Solution Approach 1:
The patent segments medical data into multiple components and distributes them across different storage locations. Sensitive personal information is separated from medical records, with each component stored in different databases or locations, so that no single point of access can retrieve complete personal information.
Solution Approach 2:
The patent introduces intermediary components such as encrypted identifiers, hash functions, and secure token systems that mediate between data access requests and actual data retrieval. These intermediaries enable data access without directly exposing personal information, acting as a buffer that protects against information leakage.
2Productivity
If clinical trial volunteer information is shared between institutions to filter duplicates, then recruitment efficiency is improved, but data security requirements increase
Solution Approach 1:
The patent creates a universal, standardized data exchange format and protocol that can be used across multiple clinical trial institutions. This universal interface enables different institutions to share volunteer information efficiently while maintaining consistent security standards, reducing the complexity of implementing institution-specific solutions.
Solution Approach 2:
The patent uses cryptographic hashing to create copies of volunteer identifiers that can be shared and compared across institutions without revealing the original personal information. These hash copies enable duplicate detection while maintaining data privacy, allowing efficient recruitment across multiple institutions without exposing sensitive data.
3Object-affected harmful factors
If offline recruitment methods are used to ensure data security, then personal information protection is improved, but recruitment efficiency deteriorates
Solution Approach 1:
The patent replaces manual, offline recruitment processes with automated electronic systems that use cryptographic methods for data protection. Instead of physical forms and manual verification, the system uses digital encryption, automated identity verification, and secure electronic data exchange, maintaining security while dramatically improving recruitment efficiency.
Data Source
AI summary
A system and method for managing medical information with enhanced personal information protection are disclosed. The system and method may generate a distributed key including a user key, an agent key, and a backup key, and manage medical data of a user, using a user agent assigned to each user and the distributed key, to prevent personal information of the user from being directly accessed from outside.
