Solution Overview

Problem

Existing online platform services lack efficient methods for authenticating and transferring qualification information between user accounts, particularly in real-time communication environments like instant messaging services, which hinders secure and accurate verification of user qualifications.

Innovation Solution

A method and apparatus for user terminals to perform qualification authentication by receiving requests, accessing authentication information, and providing qualification authentication results to external devices through identity and qualification verification processes, utilizing metadata to designate and search for target qualification information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If online platform services provide subscription services for various products, then service functionality is improved, but authentication and qualification verification efficiency deteriorates

Engineering Contradiction:
Improveservice functionalityVSAvoidauthentication efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by pre-registering qualification information in user accounts and pre-establishing authentication protocols. When a qualification authentication request is received, the system can quickly retrieve and verify the pre-stored qualification information, avoiding time-consuming verification processes during actual service delivery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary authentication mechanism that mediates between multiple service providers and users. The user terminal acts as an intermediary that stores and manages qualification information locally, enabling efficient verification without requiring direct communication between all service providers and central authentication servers, thus improving authentication efficiency while maintaining versatile service functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the system performs access authentication and searches for target qualification information, then authentication accuracy is improved, but processing time increases

Engineering Contradiction:
Improveauthentication accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system applies local quality by storing qualification information specifically in the user terminal where it is most frequently needed. This localized storage allows the terminal to quickly access and verify qualification information without requiring time-consuming queries to remote servers, thereby reducing processing time while maintaining authentication accuracy through localized verification capabilities.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs preliminary actions by pre-loading and caching qualification information in the user terminal before authentication requests occur. This advance preparation enables the terminal to immediately process authentication requests with high accuracy by comparing against pre-stored reference information, significantly reducing the time required for each authentication operation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the user terminal stores and processes authentication information locally, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The user terminal implements self-service by autonomously storing, managing, and verifying qualification information locally without requiring complex external authentication infrastructure. The terminal independently performs authentication operations using its own stored credentials and verification logic, enhancing security through local control while avoiding the need for complex server-client authentication protocols.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The user terminal applies universality by designing a multi-functional authentication system that can handle multiple types of qualification verification (e.g., age verification, professional credentials, membership status) using a single integrated local storage and verification mechanism. This universal approach allows the terminal to provide secure authentication for various services without requiring separate complex systems for each service type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Provided is a method of providing a qualification authentication result performed by a user terminal, the method including receiving a qualification authentication request for a user of the user terminal from an external device, performing access authentication to authentication information of a user account of the user in response to a selection input for the received qualification authentication request, and in response to the access authentication being successful, providing the external device with a qualification authentication result obtained by searching for target qualification information indicated by the qualification authentication request among qualification information registered in the authentication information of the user account.
