Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional centralized identity management systems are used, then identity verification can be performed through centralized authorities, but security risks increase and user control over identities is lost
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between identity holders and verifying entities. The blockchain ledger serves as a neutral mediator that stores and verifies identity credentials without requiring trust in any single centralized authority, thus maintaining verification reliability while reducing security risks associated with centralized control
Solution Approach 2:
The system enables identity holders to self-manage their credentials through cryptographic key pairs. Users can generate, store, and control their own digital identities without relying on centralized authorities to manage their personal data, giving them direct control while maintaining security through decentralized cryptographic verification
2Ease of operation
If blockchain-based decentralized identity management is implemented, then user control over identities is improved and security risks are reduced, but technical barriers and resource consumption increase
Solution Approach 1:
The patent introduces an online platform as an intermediary that provides user-friendly interfaces and automated software solutions. This mediator handles the complex blockchain interactions, cryptographic operations, and credential management behind the scenes, allowing users to control their identities without directly confronting the technical complexity of blockchain technology
Solution Approach 2:
The system creates simplified representations and interfaces that replicate traditional identity management workflows while operating on blockchain infrastructure. The online platform provides familiar user interfaces and automated processes that copy conventional identity management patterns, making decentralized identity control accessible without requiring users to understand underlying blockchain mechanics
3Adaptability or versatility
If blockchain-based identity management is used, then decentralization and user control are improved, but resource consumption and costs increase
Solution Approach 1:
The system uses selective copying of only necessary credential data to the blockchain, rather than storing complete identity information. The online platform efficiently copies and verifies only the essential verification data needed for identity validation, reducing blockchain storage requirements and the computational resources needed for verification while maintaining decentralized adaptability
Data Source
AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for claim verification. One of the methods includes: receiving, from a first entity, a request for verifying a verifiable claim (VC) that comprises a digital signature; obtaining, based on the VC, a public key associated with a second entity; determining that the digital signature is created based on a private key associated with the public key; and verifying the VC based on the determination.
