Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods of electronic record sharing are inefficient, prone to data corruption, and vulnerable to unauthorized access, requiring repetitive processes and lacking built-in authentication mechanisms.
Innovation Solution
A system utilizing a private blockchain with nodes like miner, channel, payments, and clearing nodes to validate and authorize transactions, ensuring secure and efficient record sharing by encrypting and decrypting data using public and private keys, and controlling transaction workflow within a virtual private ledger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional electronic record sharing methods are used, then individuals can send records to service providers, but the process requires repetitive record sending for each provider creating inefficiency
Solution Approach 1:
Records are uploaded once to the blockchain network and stored permanently with unique identifiers. Service providers can subsequently access and verify these records through the blockchain without requiring repeated uploads, as the records remain readily available on the distributed ledger.
Solution Approach 2:
The blockchain network acts as an intermediary layer between individuals and service providers. Instead of direct point-to-point record sharing, the blockchain mediates access by providing a centralized verification mechanism that all parties trust, eliminating the need for repetitive transfers.
2Reliability
If traditional electronic record sharing methods are used, then records can be transmitted, but they are susceptible to data corruption due to lack of built-in authentication mechanisms
Solution Approach 1:
Traditional mechanical authentication methods (passwords, physical signatures) are replaced with cryptographic hash functions. Each record is transformed into a unique hash value that serves as its digital fingerprint, providing robust authentication and integrity verification without complex mechanical systems.
Solution Approach 2:
Records are transformed through cryptographic hashing, changing their representation from original data to hash values. This parameter transformation provides built-in authentication mechanisms, as any alteration to the original record would produce a completely different hash, immediately indicating data corruption.
3Object-affected harmful factors
If traditional electronic record sharing methods are used, then records can be sent via email or web uploads, but they are more prone to attacks from unauthorized parties
Solution Approach 1:
The blockchain network provides self-service security through its distributed architecture. Each node independently verifies record authenticity using cryptographic proofs, eliminating the need for centralized security management. Unauthorized access attempts are automatically rejected by the consensus mechanism without requiring active defense.
Solution Approach 2:
Cryptographic hashing and digital signatures are applied to records before they are stored on the blockchain, creating preemptive security measures. These preliminary anti-actions ensure that even if unauthorized parties gain access to the network, they cannot alter or forge records without detection, as the cryptographic verification would fail.

AI summary
Embodiments of the present invention provide a system for authenticating records belonging to an individual or entity and providing authorized access of the records to service providers. Embodiments of the invention utilize a private blockchain to store various types of records to be conveyed to the service providers. In this way, the individual or entity may securely store on the blockchain all records relevant to service providers, then provide the service providers with secured access to the records such that the providers may access only the specific records for which they are authorized, e.g. a healthcare provider may access only the healthcare records on the blockchain.
