Tri-Party Blockchain Authentication for Secured File Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital platforms, including blockchains, face challenges in securely authenticating transactions that require restricted access due to their public visibility, leading to data breaches and security issues.
Innovation Solution
A system and method for determining an assessment value of a document related to research work, involving a server arrangement that processes information to identify technical fields, entities, and semantic relationships, comparing these to previous research work and publicly available knowledge to determine association and novelty factors, which are used to assess the document's value, while utilizing a tri-party setup with encrypted intents and consents to authenticate secured file transactions on a blockchain platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used to record transactions, then transaction verification and permanence are improved, but public visibility leads to loss of data security and restricted access
Solution Approach 1:
The patent segments the blockchain system into public and private components. The public blockchain records transaction hashes and metadata for verification, while the actual file data and sensitive information are stored in private, encrypted form. This segmentation allows transaction verification to remain public while data security is maintained through private storage and encryption.
Solution Approach 2:
The patent introduces an intermediary hashing mechanism where the actual data is not stored on the blockchain but rather cryptographic hashes of the data are stored. This intermediary approach allows the blockchain to verify transaction integrity without exposing the actual data, thus maintaining both verification capability and data security.
2Reliability
If server arrangements are used as gate keepers to authenticate transactions, then transaction security is improved, but centralized storage leads to data breaches
Solution Approach 1:
The patent extracts the authentication function from centralized servers and distributes it across the blockchain network. Instead of relying on a single server arrangement as a gate keeper, multiple nodes in the distributed blockchain network collectively authenticate transactions through consensus mechanisms, eliminating the single point of failure that makes centralized servers vulnerable to breaches.
Solution Approach 2:
The blockchain system performs self-authentication through cryptographic signatures and consensus protocols. Each participant in the network can independently verify transactions using public key cryptography, eliminating the need for trusted third-party server arrangements. The system serves itself by distributing trust across multiple nodes rather than relying on centralized authentication authorities.
