Online Learning Identity Verification With Temporary Official Certificate Data

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing online learning systems rely on biometric authentication information registered in advance, which can be compromised, leading to potential leaks of user information if official certificates are mismanaged.

Innovation Solution

A server apparatus with a temporary data storage unit that stores official certificate data for verification and deletes it after use, ensuring user registration data belong to the user while minimizing the risk of data leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If official certificate data is stored in the authentication server for verification, then user identity can be verified, but the risk of user information leakage increases

Engineering Contradiction:

Improveuser identity verificationVSAvoiduser information leakage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes the official certificate data from the authentication server after verification is complete. The server only retains verification results, not the actual certificate data, thereby eliminating the source of potential data leakage while maintaining verification functionality

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements a process where official certificate data is temporarily stored during verification, then automatically discarded (deleted) after use. This temporary storage and subsequent deletion ensures that sensitive data is available when needed but does not remain in the system, preventing long-term leakage risks

Inventive Principle:

Principle #34Discarding and recovering

2Ease of operation

If biometric authentication information is registered in advance, then authentication can be performed, but the information may be compromised leading to spoofing

Engineering Contradiction:

Improveauthentication processVSAvoidauthentication security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent performs verification of user registration data against official certificate data before the user completes registration. This preliminary verification ensures that the data being registered actually belongs to the user, preventing future spoofing while maintaining smooth authentication

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces official certificate data as an intermediary verification medium. Instead of directly trusting self-reported biometric data, the system uses the official certificate (which the user possesses) as intermediate proof of identity, making spoofing difficult while keeping the authentication process user-friendly

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A server apparatus includes: a registration data storage unit that stores user registration data corresponding to information written in an official certificate; a temporary data storage unit that temporarily stores official certificate data; and a verification processing unit that verifies the user registration data stored in the registration data storage unit against the official certificate data stored in the temporary data storage unit, wherein the temporary data storage unit does not retain the official certificate data used in the verification, after the verification in the verification processing unit.
