Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional digital signature systems are used, then the signing process is simple and fast, but the system lacks robust mechanisms to verify the identity of the signatory and detect document tampering
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between the digital signature process and identity verification. The blockchain serves as a trusted mediator that stores and verifies digital identities, signing credentials, and document hashes without requiring direct complex verification mechanisms in the signature system itself. This resolves the contradiction by enhancing reliability through the blockchain intermediary while keeping the signature process relatively simple.
Solution Approach 2:
The system performs preliminary actions by pre-registering digital identities and credentials on the blockchain before the actual signing process. Document hashes are also recorded on the blockchain in advance. This preliminary setup on the blockchain enables rapid verification during signing without adding complexity to the moment-of-signing process, thus improving reliability without worsening operational simplicity.
2Reliability
If identity verification mechanisms are added to digital signature systems, then security against identity theft improves, but the ease of operation decreases
Solution Approach 1:
The blockchain system operates as a self-service verification mechanism where the integrity of identity verification is maintained automatically through cryptographic proofs and smart contracts. The system self-validates identities and document integrity without requiring manual intervention or complex user-facing verification steps, thus improving security while preserving ease of operation.
Solution Approach 2:
The patent replaces traditional mechanical identity verification methods (manual ID checks, physical presence verification) with cryptographic mechanisms based on blockchain technology. This substitution uses mathematical proofs and digital signatures instead of physical verification processes, enhancing security against identity theft while maintaining or even improving the ease of operation through automated digital validation.
3Reliability
If document integrity verification is implemented, then protection against document tampering improves, but the complexity of the system increases
Solution Approach 1:
The patent extracts the complex document integrity verification functionality into a separate blockchain-based layer. Instead of embedding complex verification algorithms throughout the document management system, the system extracts the core verification function to the blockchain, where document hashes are stored and verified independently. This resolves the contradiction by improving document integrity protection while keeping the main system architecture relatively simple through functional extraction.
4Reliability
If blockchain technology is integrated into digital signature systems, then security and reliability are enhanced, but the device complexity and computational requirements increase
Solution Approach 1:
The patent segments the digital signature system into distinct functional layers: the traditional signature generation layer and the blockchain-based verification layer. Each layer handles specific tasks independently, with clear interfaces between them. This segmentation resolves the contradiction by allowing blockchain integration for enhanced reliability while keeping each segment's complexity manageable and well-defined.
