Solution Overview

Problem

The existing user authentication systems that rely on variable and unique authentication information stored on an authentication server can lead to inaccuracies in user authentication, where changes in authentication information cause successful authentication of the wrong user or failure of the correct user to authenticate.

Innovation Solution

An information processing apparatus and system that stores both variable and unique authentication information and invariant and unique fixed information for each user, using a processor to compare received authentication information with stored combinations to ensure accurate user authentication by combining the authentication information and fixed information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If only variable and unique authentication information is stored in the authentication server for user authentication, then the authentication system is simple and flexible, but the accuracy of user authentication deteriorates when authentication information changes

Engineering Contradiction:

Improveauthentication system flexibilityVSAvoiduser authentication accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The authentication information is segmented into two distinct parts: variable authentication information (stored on authentication server) and fixed authentication information (stored on both authentication server and terminal apparatus). This segmentation allows the system to maintain flexibility through variable information while ensuring accuracy through fixed information that remains unchanged.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Fixed authentication information acts as an intermediary element that mediates between the need for flexible authentication (variable information) and accurate user identification. By introducing this intermediate fixed information layer, the system resolves the contradiction between adaptability and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If authentication information is changed in the authentication server for updated user data, then the authentication system remains adaptable, but incorrect authentication occurs where users are authenticated as wrong identities

Engineering Contradiction:

Improveauthentication information update capabilityVSAvoiduser identity verification accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

Fixed authentication information is preliminarily stored on both the authentication server and the terminal apparatus before any changes occur. This preliminary action ensures that even when variable authentication information changes, the fixed information remains as a reliable reference for accurate user identity verification.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system distinguishes between parameters that should change (variable authentication information for adaptability) and parameters that should remain constant (fixed authentication information for precision). By controlling which parameters change and which remain stable, the system maintains both adaptability and verification accuracy.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If variable authentication information is used alone for authentication, then the system operation is simple, but authentication failures occur when information is reassigned to different users

Engineering Contradiction:

Improveauthentication process simplicityVSAvoidauthentication correctness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The authentication process merges two types of information: variable authentication information (for simple operations and updates) and fixed authentication information (for ensuring correctness). By combining these two elements, the system maintains ease of operation while preventing authentication errors.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The authentication system uses a composite approach, combining variable information (analogous to one material) and fixed information (analogous to another material) to create a more robust authentication mechanism that leverages the strengths of both components.

Inventive Principle:

Principle #40Composite materials
