Blockchain Biological Sample Registry for Research Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no comprehensive mechanism for third-party researchers to access physical biological specimens or comprehensive information about stored biological specimens, requiring multiple inquiries to different medical institutions for sample access and data retrieval.
Innovation Solution
A blockchain-based system for managing and storing biological samples and related information, enabling access through a network of computing nodes, using smart contracts for secure and transparent transaction management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If third-party researchers directly query multiple medical institutions for sample access, then comprehensive sample information can be obtained, but the process becomes arduous and time-consuming
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that acts as a centralized registry for biological sample information. Instead of researchers directly querying multiple medical institutions, the system provides a single point of access where sample metadata, location, and availability information are stored on a distributed ledger. This intermediary layer consolidates information from multiple sources while maintaining data integrity through blockchain technology, thereby reducing the time and effort required for sample discovery.
2Reliability
If multiple medical institutions store sample information independently, then data security and control are maintained, but accessibility for researchers becomes difficult
Solution Approach 1:
The blockchain system serves multiple functions simultaneously: it acts as a secure distributed ledger for storing sample information, a centralized search interface for researchers, and a communication platform between medical institutions and researchers. The universal nature of the blockchain protocol enables different institutions with varying systems to interact through a common standard, improving accessibility while maintaining each institution's control over their own data through cryptographic security.
3Ease of operation
If comprehensive sample data is centralized in one location, then researcher access is simplified, but security and control by individual institutions is reduced
Solution Approach 1:
The system segments data into two categories: sample metadata and physical sample control. Metadata (location, type, availability, contact information) is stored on the blockchain to enable easy researcher access and searching, while actual physical sample control and sensitive patient information remain with the originating medical institutions. This segmentation allows simplified access for researchers through the blockchain interface while maintaining security and institutional control over the actual samples and sensitive data.
