Valuables Management System Using Data Segmentation for Blockchain Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain systems for cryptocurrency transactions lack robust security measures, as they rely on public verification and consume significant computational power for Proof of Work, making them vulnerable to unauthorized access and power-intensive.
Innovation Solution
A valuables management system that divides data into partial and body data, encrypts partial data, and updates hash values at intervals, ensuring that even if body data is leaked, it has no value on its own and cannot be used to recover the valuables, while reducing storage and computational requirements by storing only partial data in the blockchain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire valuables data is stored in the blockchain, then the verification of transaction fairness is complete, but the storage area and computational power required become excessively large
Solution Approach 1:
The patent divides the valuables data into partial data (first predetermined size from the beginning) and body data (remaining data). Only the partial data is stored in the blockchain, while the body data is stored separately. This segmentation allows the system to maintain verification fairness through the partial data while significantly reducing the storage requirements in the blockchain.
2Reliability
If the entire valuables data is stored in the blockchain, then all transaction records are available, but the computational power consumption for Proof of Work becomes excessively large
Solution Approach 1:
The patent segments the valuables data into partial data and body data, storing only the partial data in the blockchain for Proof of Work verification. This reduces the computational power consumption significantly while maintaining the ability to verify transaction fairness through the partial data and its associated hash values.
3Ease of operation
If the body data is stored in the colony server, then the data is accessible to users, but the risk of unauthorized access and data leakage increases
Solution Approach 1:
The patent divides the data such that the body data is stored in the colony server but the partial data (which includes critical identification information) is stored in the blockchain. This segmentation means that even if the body data is leaked from the colony server, the leaked data cannot be used to access or recover the valuables without the corresponding partial data from the blockchain.
Solution Approach 2:
The patent uses hash values as an intermediary mechanism. The hash value of the partial data is stored in the blockchain and linked to the body data. This intermediary hash value acts as a verification mechanism that prevents unauthorized access to the body data, as the hash value must match the partial data in the blockchain to validate the transaction.
4Volume of stationary object
If the partial data is stored in the blockchain, then the storage area is reduced, but the verification process becomes more complex
Solution Approach 1:
The patent segments the data into partial data and body data, storing only the partial data in the blockchain. This reduces the storage area while the verification process remains relatively simple through hash value comparison. The system only needs to verify that the hash value of the partial data matches the stored hash value in the blockchain, which is a straightforward verification process.

AI summary
In a blockchain, contents of a transaction are basically made public, and a malicious person can find system vulnerability of the blockchain. The person is likely to exploit the vulnerability and cause leak of cryptocurrency to an unintended third party through unauthorized access or the like. Thus, it cannot be said that sufficient security measures are taken. In the present invention, a colony server stores partial data containing data of a predetermined size from a beginning of valuables data received from a terminal, and a center server stores body data containing data of the predetermined size +1 and thereafter. Thus, the valuables data is managed in a divided manner. Also, even if the body data is leaked from the colony server through unauthorized access or the like, the body data is merely part of the valuables data, and has no value on its own. Thus, the present invention provides a system and the like for achieving robust security against unauthorized access.
