Medication Information Management System with Blockchain Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vaccination record systems lack reliability as they only confirm completion of vaccination without verifying post-medication conditions, and are susceptible to unauthorized changes, lacking effective countermeasures for tampering.
Innovation Solution
A medication information management system that transmits and stores both medication completion and post-medication information, creating certification that includes adverse reactions, and employs a blockchain-based trail management system for verification to ensure authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only medication completion information is stored in the server, then the system is simple and easy to operate, but the reliability of vaccination certification is insufficient and cannot verify post-medication conditions
Solution Approach 1:
The patent segments the vaccination record into multiple components: medication completion information, post-medication condition information, and verification information. Each component is stored and managed separately but linked through the distributed ledger, allowing comprehensive verification while maintaining system modularity and manageability
Solution Approach 2:
The patent introduces a distributed ledger (blockchain) as an intermediary between the medication administration system and the certification verification system. This intermediary immutably records both medication completion and post-medication conditions, providing trusted verification without requiring direct trust between all system participants
2Reliability
If vaccination records are stored in a centralized server, then the system is easy to operate, but it is susceptible to unauthorized changes and tampering
Solution Approach 1:
The distributed ledger acts as a neutral intermediary that immutably stores verification information including medication completion status and post-medication conditions. Once data is recorded on the distributed ledger, it cannot be altered without detection, providing tamper-proof verification while keeping the overall system architecture relatively simple
Solution Approach 2:
The patent uses a standardized data structure for storing vaccination information on the distributed ledger, ensuring consistent formatting and validation of medication completion information and post-medication conditions. This homogenized approach simplifies verification processes while maintaining high integrity standards
Data Source
AI summary
Verification of not only medication completion information but also information indicating post-medication conditions can be realized. The medication completion information indicating the fact of the medication having been administered to a target recipient is obtained, and the obtained medication completion information is stored in association with the unique identification information of the target recipient. The post-medication information indicating the condition of the target recipient after the medication is obtained from the user terminal, and the obtained post-medication information is stored in association with the medication completion information. Medication certification information is created based on the stored medication completion information and post-medication information, and the process for submitting the created medication certification information from the target recipient to an organization is controlled.
