Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in personalized cancer treatment and autoimmune disease therapies lies in ensuring the authenticity and integrity of genetic data, vaccine recipes, and drug manufacturing processes, particularly in the distribution of personalized drugs where individualized peptides are involved, necessitating mechanisms to verify the origin and integrity of genome data, recipe data, and drug specifications.
Innovation Solution
An information processing system utilizing blockchain technology to record and verify hash values generated from target content, ensuring authenticity by matching hash values across different stages of the drug creation and distribution process, involving terminals and management systems to secure the integrity of genome information, vaccine recipes, and drug manufacturing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personalized drug creation processes are implemented involving multiple organizations (gene analysis, recipe creation, drug manufacturing), then treatment effectiveness and personalization are improved, but ensuring authenticity and integrity of data across distributed parties becomes more complex
Solution Approach 1:
The patent introduces a management system as an intermediary that coordinates between gene analysis organizations, recipe creation organizations, and drug manufacturing organizations. This management system uses blockchain technology to mediate data exchange and verification, reducing the complexity of direct multi-party coordination while maintaining personalization capabilities.
Solution Approach 2:
The patent creates cryptographic copies (hash values) of sensitive data that can be distributed and verified without sharing the actual data. By storing hash values on blockchain and comparing them against original data, the system enables authentication across distributed organizations without requiring them to handle or trust each other's raw data, thus simplifying the distribution process.
2Reliability
If hash value verification mechanisms are implemented across multiple terminals and systems, then data authenticity and integrity are improved, but the verification process and system operations become more complex
Solution Approach 1:
The patent implements self-service verification mechanisms where each terminal automatically generates, stores, and compares hash values without requiring manual intervention. The system autonomously verifies data integrity by comparing stored hash values with newly generated ones, reducing operational complexity while maintaining high reliability through automated cryptographic verification.
Solution Approach 2:
The patent establishes feedback loops where verification results are automatically recorded on the blockchain and used to confirm or reject data transactions. This automated feedback mechanism simplifies operations by providing immediate verification outcomes and enabling the system to self-correct or alert operators only when anomalies occur, rather than requiring constant manual monitoring.
Data Source
AI summary
An information processing system comprising a first terminal, a second terminal, and a management system, in which the first terminal outputs a first hash value from data including at least target content, and transmits first verification data including either the first hash value or information based on the first hash value, the management system records the first verification data received from the first terminal in a blockchain, the management system reads the first verification data recorded in the blockchain and transmits the data to the second terminal, and the second terminal acquires a first hash value included in the first verification data received from the management system, acquires target content, generates a second hash value from the target content, and determines whether the first hash value matches the second hash value.
