Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If IPFS decentralized file system is used for document storage, then redundancy and fault tolerance are improved, but security features (user representation, file permissions, encryption) are lacking

Engineering Contradiction:

Improvefault toleranceVSAvoidsecurity vulnerabilities

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system segments security management by introducing separate cryptographic key pairs for each user, with public keys stored in IPFS for user representation and private keys kept locally for authentication. This segmentation allows IPFS to handle storage reliability while cryptographic layers handle security independently.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces cryptographic hashes and public keys as intermediaries between users and IPFS stored content. These intermediaries enable secure document sharing, permission management, and user identification without requiring IPFS itself to implement security features, thus resolving the contradiction between using IPFS for reliability and maintaining security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If documents are stored in decentralized IPFS network, then accessibility and scalability are improved, but data confidentiality and integrity are compromised without encryption

Engineering Contradiction:

ImproveaccessibilityVSAvoiddata exposure risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary encryption of documents before storing them in IPFS. Documents are encrypted with recipient public keys or shared secret keys derived from public key pairs before being uploaded to the decentralized network. This preliminary cryptographic action ensures that even though IPFS provides broad accessibility, the actual document content remains confidential and integrity-protected throughout the decentralized storage and retrieval process.

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If cryptographic authentication and encryption are implemented, then security and confidentiality are improved, but system complexity increases

Engineering Contradiction:

Improvesecurity protectionVSAvoidsystem architecture complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements a universal cryptographic framework where public key pairs serve multiple functions: user identification in IPFS, document encryption, authentication verification, and permission management. This multi-functionality reduces overall system complexity by using a single cryptographic mechanism for multiple security needs rather than implementing separate systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Users generate and manage their own cryptographic key pairs locally without requiring centralized key management infrastructure. The system enables self-service authentication and encryption where users independently manage their security credentials, eliminating the need for complex centralized security management systems while maintaining strong security protection.

Inventive Principle:

Principle #25Self-service

AI summary

A user and business collaboration and document management solution is described. The solution utilizes the InterPlanetary File System (IPFS) or similar distributed and decentralized storage methods, in addition to the Publish/Subscribe (PubSub) message protocol or similar distributed messaging methods. As a fully decentralized and distributed solution, information is shared through cryptographically secure and resilient Web 3.0 mechanisms. The solution provides a number of secure collaboration services. Users can securely add, update, delete, archive and share documents on the IPFS file system. Local directory synchronization automates this task. A localized encryption key and secrets vault is used to protect data encryption keys, authentication credentials, and related secrets.
