Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual KYC checks and centralized verification systems are used, then entity information can be verified, but processing overheads and costs increase significantly
Solution Approach 1:
The patent replaces manual mechanical verification processes with automated cryptographic verification. Entities use digital signatures and public-key cryptography to verify information automatically, eliminating the need for manual document checking and reducing processing overhead while maintaining or improving verification reliability.
Solution Approach 2:
The patent introduces blockchain technology as a decentralized intermediary that enables direct peer-to-peer verification without centralized authorities. The blockchain serves as a trusted mediator that records and verifies entity information, allowing entities to validate each other's data without requiring manual intervention or centralized processing.
2Reliability
If repeated verification checks are performed across multiple entities, then information accuracy is maintained, but network bandwidth and processing resources are consumed
Solution Approach 1:
The patent implements preliminary verification where entity information is verified once and the results are stored on the blockchain. Subsequent entities can retrieve and verify this pre-validated information through cryptographic proof, eliminating the need for repeated verification checks and reducing network resource consumption while maintaining information accuracy.
Solution Approach 2:
The patent allows entities to copy and reuse verified information from the blockchain without requiring re-verification. Once information is validated and recorded, it can be efficiently copied and referenced by multiple entities, reducing redundant processing and network bandwidth consumption while maintaining accuracy through cryptographic integrity checks.
3Ease of operation
If personal documentation is transmitted over public networks, then verification can be performed, but security risks increase
Solution Approach 1:
The patent extracts sensitive personal information from direct transmission over public networks. Instead of sharing actual documentation, entities share cryptographic proofs and hashed representations of their information stored on the blockchain. This extraction of essential verification data without exposing sensitive originals eliminates security risks while maintaining verification convenience.
Solution Approach 2:
The patent uses disposable cryptographic tokens and temporary verification credentials that can be generated and discarded. Entities create ephemeral proof objects for verification purposes that contain no sensitive personal data, use them once for verification, and then discard them, eliminating security risks associated with transmitting and storing personal documentation.
4Reliability
If stronger verification checks are implemented, then trustworthiness improves, but transaction costs and processing time increase
Solution Approach 1:
The patent implements periodic verification where strong verification is performed initially and recorded on the blockchain, followed by efficient periodic checks using cryptographic proofs. The initial thorough verification establishes trustworthiness, while subsequent periodic validations using stored cryptographic data maintain this trustworthiness at low cost and high speed, resolving the contradiction between strong verification and transaction efficiency.
