Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized identity verification system is used, then user authentication can be performed through installed programs or applications, but personal information may be leaked or abused and the system is incompatible with existing applications
Solution Approach 1:
The patent introduces a blockchain-based decentralized identifier (DID) system as an intermediary between users and service providers. The DID system acts as a mediator that enables identity verification without exposing personal information, using cryptographic keys and blockchain technology to verify identities while keeping sensitive data private and decentralized.
Solution Approach 2:
The patent replaces the mechanical centralized identity verification system with a blockchain-based decentralized system. Instead of relying on centralized databases and installed authentication programs, the system uses distributed ledger technology, cryptographic signatures, and smart contracts to perform identity verification, eliminating the need for personal information storage and reducing security risks.
2Reliability
If a centralized identity verification system is used, then authentication can be performed through installed programs, but the system is incompatible with existing applications and programs
Solution Approach 1:
The patent creates a universal identity verification system based on blockchain DID that can be integrated with various existing applications and services. The system uses standardized cryptographic protocols and blockchain interfaces that are compatible across different platforms, allowing the same DID system to serve multiple purposes and work with diverse applications without requiring separate authentication mechanisms.
Solution Approach 2:
The blockchain DID system serves as a universal intermediary layer between different applications and identity verification needs. By using standardized blockchain interfaces and cryptographic protocols, the system can mediate authentication across various platforms and services, ensuring compatibility without requiring applications to be modified or reinstalled.
3Productivity
If open badge data is stored in a centralized system, then badge issuance and verification can be processed, but data integrity cannot be guaranteed and forgery is possible
Solution Approach 1:
The patent replaces centralized badge storage and verification systems with a blockchain-based decentralized system. Badge data is stored as immutable records on the blockchain, with each badge containing cryptographic proofs of authenticity. The verification process uses blockchain consensus mechanisms and cryptographic signature validation instead of centralized database checks, ensuring data integrity and preventing forgery while maintaining processing efficiency.
Solution Approach 2:
The patent uses cryptographic copying and hashing mechanisms to verify badge authenticity. Instead of storing and comparing original badge data centrally, the system creates cryptographic hashes and digital signatures of badge information, storing these immutable copies on the blockchain. Verification is performed by comparing cryptographic proofs rather than original data, ensuring integrity without requiring centralized storage of sensitive information.
