Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional identity verification methods using physical documents are insecure and require physical presence, lacking remote verification capabilities and being susceptible to fraud, as they cannot ensure the authenticity of identity data.

Innovation Solution

A digital identity network interface system that allows secure release of identity data through a permissioned blockchain network, enabling remote verification by translating digital identity requests into query formats supported by the network, and ensuring data is only released after authentication and consent from the individual associated with the data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical identity documents are used for verification, then identity authentication can be performed, but the system is insecure and susceptible to fraud

Engineering Contradiction:

Improveidentity verification securityVSAvoidfraud risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces physical identity documents with digital copies stored on a blockchain network. Instead of verifying physical passports or driver's licenses, the system creates and verifies digital representations of identity data on the blockchain, eliminating the security vulnerabilities of physical document verification while maintaining authentication capability

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces a blockchain network as an intermediary between identity holders and verification systems. The blockchain acts as a trusted mediator that stores and verifies identity data without requiring direct interaction between parties, providing secure, tamper-proof verification while eliminating fraud risks associated with physical document inspection

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If physical identity documents are reviewed, then identity verification can be completed, but physical presence is required

Engineering Contradiction:

Improveverification process simplicityVSAvoidremote verification capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical process of physical document inspection with digital verification through blockchain technology. Instead of manually examining physical passports or licenses, the system uses automated blockchain verification to confirm identity data, enabling remote verification while maintaining process simplicity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a universal digital identity verification system that can be accessed from any location through digital devices. The blockchain-based identity data can be verified across multiple platforms and jurisdictions, providing both operational simplicity and remote verification capability simultaneously

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If physical identity documents are used, then identity data can be verified, but data authenticity cannot be ensured

Engineering Contradiction:

Improveidentity data authenticityVSAvoiddata verification trustworthiness

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent implements preventive measures by storing identity data on a blockchain network before verification is needed. The blockchain's inherent immutability and cryptographic security provide beforehand protection against data tampering, ensuring that identity data remains authentic and trustworthy throughout the verification process without requiring additional trust mechanisms

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

There is a provided a digital identity network interface system that may include a communications module and a processor. The processor may be configured to receive a signal representing a digital identity request, the digital identity request defining one or more scopes associated with the request, at least one of the scopes identifying a data type associated with the request, generate a query based on the scopes by translating at least one of the scopes into a query having a query format associated with a digital identity network, the digital identity network storing data associated with a plurality of users, send a signal representing the query to the digital identity network, send a link to an authorization device, after successful authentication, obtain data associated with the digital identity request from the digital identity network, and release at least some of the data.
