Solution Overview

Problem

Existing digital identity and presence verification solutions fail to provide a unified, privacy-preserving mechanism to verify the authenticity of trusted credential data and the live presence of the rightful bearer, often compromising privacy and relying on centralized infrastructure.

Innovation Solution

A method and system that verifies the identity of an individual associated with a trusted credential using biometric data and a digital signature, ensuring real-time presence verification without central authority involvement, by comparing live biometric data with trusted credential data and initiating state changes based on cryptographic verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a trusted credential data object is transmitted to third parties for verification, then identity verification is enabled, but personal data exposure and privacy loss occur

Engineering Contradiction:

Improveidentity verification accuracyVSAvoidpersonal data exposure

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts only the essential verification elements (cryptographic proofs, biometric hashes) from the complete personal data set. The trusted credential system extracts identity proof without extracting unnecessary personal information, and transmits only the minimal data required for verification to third parties, thereby preventing unnecessary personal data exposure while maintaining verification reliability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a trusted credential system as an intermediary between the user and third-party verifiers. This intermediary handles the complex verification process internally, allowing third parties to receive verification results without directly accessing sensitive personal data. The intermediary mediates the interaction by transforming personal data into cryptographic proofs that preserve privacy while enabling verification

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If centralized infrastructure is used for identity verification, then verification reliability is improved, but system complexity and single point of failure risks increase

Engineering Contradiction:

Improveverification trustworthinessVSAvoidcentralized infrastructure dependency

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the centralized verification function into distributed components. Each user device contains a local trusted credential wallet that can independently verify credentials without requiring continuous connection to a central authority. The verification capability is segmented and distributed to individual devices, eliminating the single point of failure while maintaining verification reliability through cryptographic proofs

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent enables user devices to perform self-verification of trusted credentials locally without requiring centralized infrastructure. The device can independently verify the authenticity of credentials in its wallet using embedded cryptographic verification, allowing the system to serve itself without external centralized control, thereby reducing infrastructure complexity while maintaining reliability

Inventive Principle:

Principle #25Self-service

3Measurement precision

If biometric data is collected for presence verification, then presence authentication accuracy is improved, but privacy concerns and data security risks worsen

Engineering Contradiction:

Improvepresence verification accuracyVSAvoidbiometric data security risks

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the essential biometric verification outcome (match/no-match result or cryptographic hash) from the complete biometric data. Instead of storing or transmitting raw biometric data, the system extracts and processes only the verification result or a cryptographic representation, thereby maintaining high verification accuracy while minimizing privacy exposure and security risks associated with biometric data storage

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms biometric data from its original form into cryptographic parameters (hashes, encrypted representations, or verified proofs) that preserve the verification capability while eliminating the privacy and security risks of storing raw biometric data. The parameter transformation maintains the essential verification function while changing the data form to be privacy-preserving

Inventive Principle:

Principle #35Parameter changes

AI summary

The present invention relates to the domain of digital identity verification and presence verification. More particularly the invention provides identity verification methods and systems for verifying the identity of an individual associated with a trusted credential or a trusted credential data object. The trusted credential is stored on or is accessible at or through a user device—and has been generated by a trusted credential system that is distinct from (and that is located remotely from) the user device, while simultaneously verifying in real time, the live presence of the individual associated with the trusted credential, at the user device.
