Solution Overview

Problem

Current identity verification methods are inefficient and insecure, as they require repeated uploads of certifying materials and direct contact with original identity information, leading to low verification efficiency and security risks.

Innovation Solution

An identity verification method that involves a declaration issuing device generating a target declaration and a first tree, where the object terminal transmits the target declaration and bypass nodes to a verification device for verification, reducing the need for repeated uploads and enhancing security by not contacting original identity information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If centralized identity verification is performed by directly contacting original certifying materials, then verification security is maintained, but verification efficiency deteriorates due to repeated uploads

Engineering Contradiction:
Improveverification efficiencyVSAvoidverification security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent performs identity verification in advance and generates a verification declaration before the actual verification request occurs. The declaration issuing device authenticates the object's identity attributes beforehand, creates a verification declaration containing the authentication result, and stores it in a declaration database. When a verification request comes later, the system only needs to retrieve and verify the pre-generated declaration using a digital signature, eliminating the need for repeated original material verification while maintaining security through cryptographic validation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If original certifying materials are repeatedly contacted for verification, then verification accuracy is ensured, but information security deteriorates due to identity information exposure

Engineering Contradiction:
Improveverification accuracyVSAvoididentity information exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the essential verification information from the original certifying materials and stores it in the form of a verification declaration in the declaration database. Instead of repeatedly accessing and exposing the original sensitive identity materials, the system extracts only the necessary authentication results and stores them as structured declarations with digital signatures. This extraction approach maintains verification accuracy while preventing exposure of the original identity information.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The verification declaration acts as an intermediary between the original certifying materials and the verification request. The declaration issuing device creates this intermediate representation that contains the authentication result without exposing the original sensitive materials. The verification device then validates this intermediary declaration using digital signature verification, ensuring both accuracy and security without direct contact with original identity information.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If pre-generated verification declarations are used, then verification efficiency is improved, but device complexity increases due to tree structure management

Engineering Contradiction:
Improveverification efficiencyVSAvoiddeclaration management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the verification declaration into a hierarchical tree structure where the root node contains a digest of all leaf nodes, and intermediate nodes contain digests of their child nodes. This segmentation allows the verification device to efficiently verify declarations by only needing to validate the cryptographic hash chain from leaf to root, rather than managing the entire declaration structure. The segmentation transforms a complex management problem into a simple cryptographic verification process.

Inventive Principle:
Principle #1Segmentation
