Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional central server architectures for digital information management lack user control and anonymity, as they rely on a single central authority for authentication and data control, posing security vulnerabilities and limiting user autonomy.

Innovation Solution

A decentralized platform uses a processor-executable engine to generate cryptographically secure and reusable distributed identities, associating them with a blockchain for secure and private data management, enabling user-controlled access and anonymity through an owner authorization flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a central server architecture is used for digital information management, then authentication and verification can be implemented through a single source of control, but security vulnerabilities increase and user anonymity is compromised

Engineering Contradiction:

Improveauthentication verificationVSAvoidsecurity vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the centralized authentication system into distributed identity verification across multiple nodes. Instead of relying on a single central authority, the system divides authentication responsibilities across a decentralized network, where each node can independently verify identities through cryptographic proofs, thereby maintaining reliability while eliminating the single point of failure that creates security vulnerabilities

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces cryptographic intermediaries (digital signatures, hash functions, and zero-knowledge proofs) that mediate between users and the system without requiring direct trust in a central authority. These cryptographic intermediaries enable authentication verification while preserving user anonymity and eliminating the security risks associated with centralized control

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a central server architecture is used for digital information management, then authentication control can be centralized, but user anonymity is limited

Engineering Contradiction:

Improveauthentication controlVSAvoiduser anonymity

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent extracts the identifying information from the authentication process. Users can authenticate themselves through cryptographic proofs that verify their identity without revealing personal identifying details. The system takes out the connection between authentication credentials and personal identity information, allowing users to maintain anonymity while enabling centralized-like control through cryptographic verification

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Cryptographic intermediaries serve as mediators that enable authentication control without compromising user anonymity. Digital signatures and zero-knowledge proofs act as intermediaries that verify user identities while preserving anonymity, allowing the system to maintain ease of operation for authentication control while preventing the loss of user anonymity information

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If a third-party central authority is used to manage user identities, then access control to digital information can be implemented, but user control over digital information is reduced

Engineering Contradiction:

Improveaccess controlVSAvoiduser control

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent enables users to perform self-service authentication and access control through cryptographic keys and digital signatures. Users independently manage their own identity verification without requiring third-party intervention, allowing them to maintain full control over their digital information while still enabling access control mechanisms. The system provides ease of operation for access control while maximizing user control through self-service capabilities

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent inverts the traditional model where the authority controls access to user information. Instead, users control access to their own information through cryptographic mechanisms, and the system adapts to user-defined access rules. This inversion allows access control to be implemented while giving users ultimate control over their digital information, enhancing both ease of operation and user adaptability

Inventive Principle:

Principle #13The other way round (Inversion)
