Solution Overview

Problem

Existing identity verification systems face challenges in person-to-person non-face-to-face interactions, particularly in verifying identities between individuals at short distances, which are inconvenient and time-consuming, especially in large gatherings, and do not support efficient social distancing measures.

Innovation Solution

A person-to-person non-face-to-face identity verification system using wireless communication that registers user registration information including user identifier, public key, and terminal identifier on off-chain or on-chain, allowing terminals to exchange and verify electronically signed certificates using public keys, generating integrated certificates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional face-to-face identity verification methods are used, then personal information can be verified, but it requires close physical contact which prevents social distancing

Engineering Contradiction:

Improveidentity verification accuracyVSAvoidphysical contact risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical face-to-face verification process with a wireless communication system using Bluetooth Low Energy (BLE) technology. Terminals automatically exchange and verify certificates without requiring physical proximity or visual contact, substituting the mechanical interaction with automated wireless communication while maintaining verification reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces certificates as an intermediary element between individuals. Instead of direct personal information exchange, terminals communicate through verified certificates that contain necessary identification data, enabling indirect verification that eliminates the need for close physical contact while ensuring identity authenticity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If traditional business card exchange methods are used, then personal contact information can be shared, but it takes a lot of time for large groups and requires physical interaction

Engineering Contradiction:

Improveinformation exchange convenienceVSAvoidverification time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent implements self-service functionality where terminals automatically perform certificate exchange and verification processes without manual intervention. When terminals come within wireless range, they automatically initiate the certificate exchange process, eliminating the need for manual business card distribution and reducing time loss while improving operational ease

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent performs preliminary actions by pre-registering certificates and public keys in the system before actual verification needs arise. This preparation allows terminals to immediately exchange and verify certificates without time-consuming setup processes, enabling rapid information exchange in large groups

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If distributed ID systems are used, then remote verification is possible, but they cannot be used in person-to-person non-face-to-face identification due to legal requirements for real name verification

Engineering Contradiction:

Improveremote verification capabilityVSAvoidreal name verification compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the advantages of distributed ID systems (automated remote verification) with traditional real-name verification requirements. By combining certificate-based automated exchange with legally compliant identification data, the system achieves both remote operational capability and real-name verification compliance for person-to-person non-face-to-face identification

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent changes the verification parameters from requiring physical presence or centralized registration to using wireless communication distance and certificate-based identification. This parameter change enables the system to meet legal real-name verification requirements while operating in a decentralized, automated manner suitable for person-to-person non-face-to-face scenarios

Inventive Principle:

Principle #35Parameter changes

AI summary

A person-to-person non-face-to-face identity verification system using wireless communication is disclosed. The non-face-to-face identity verification system according to the present invention mutually exchanges a first certificate signed with a user identifier and a private key of a terminal user and a second certificate signed with a user identifier and a private key of a terminal user of a second terminal from the second terminal, verifies the received certificates with a public key of each terminal registered on on/off-chain, combines the verified certificate and a self-generated certificate to generate an integrated certificate. Accordingly, since the electronically signed confirmations are exchanged with each other and verified with public keys registered on the on/off-chain, it is possible to exchange the verified certificates non-face-to-face.
