Solution Overview

Problem

Existing authentication systems face challenges in maintaining high security without waste when performing multistage authentication within a facility, as they often require redundant authentication processes across multiple points.

Innovation Solution

An authentication system that determines the necessary authentication information for each user based on their authentication history, allowing entry into a second area by either using authentication information acquired at the first area or acquiring additional biological information via a user terminal if not previously registered, thereby optimizing authentication processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multistage authentication is performed at each authentication point, then security level is improved, but authentication processing time and system complexity increase

Engineering Contradiction:

Improvesecurity levelVSAvoidauthentication processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary authentication at the first authentication point and stores the authentication result. When the user reaches the second authentication point, the system retrieves the stored authentication result instead of requiring complete re-authentication, thereby reducing processing time while maintaining security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Different authentication points have different authentication requirements. The first authentication point requires basic authentication, while the second authentication point utilizes the previous result and only requires verification. This local differentiation optimizes the balance between security and processing time at each specific location

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple authentication devices are installed at each authentication point, then authentication capability is improved, but device complexity and cost increase

Engineering Contradiction:

Improveauthentication capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The authentication system is designed to accept multiple types of authentication information (biometric data, personal information, IC card data) through a unified authentication framework. This allows the same authentication device to perform multiple authentication functions without requiring separate specialized devices for each authentication type

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses an authentication information acquisition apparatus as an intermediary that can obtain different types of authentication information from various sources (user terminal, IC card reader, camera) and process them through a unified authentication flow, reducing the need for multiple specialized devices at each authentication point

Inventive Principle:

Principle #24Intermediary (Mediator)
