Problem

Existing authentication technologies are limited in their ability to efficiently handle multiple services with different authentication levels and require excessive user effort for procedures such as address changes, as they cannot adapt to various procedures efficiently.

Innovation Solution

An authentication system utilizing dynamic biometric authentication that combines face and voice recognition, including face authentication, voice authentication, and lip synchronization, performed via a mobile device to efficiently authenticate users across multiple services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional authentication technologies are used, then authentication can be performed for specific procedures, but the system cannot efficiently handle multiple services with different authentication levels and various procedures such as address changes across multiple institutions

Engineering Contradiction:
Improveauthentication system versatilityVSAvoidauthentication efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements a universal authentication system where a single authentication result can be utilized across multiple services and institutions. The authentication information management unit stores authentication results that can be shared by financial institutions, public institutions, and other services, eliminating the need for repeated authentication procedures at different institutions.

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

Solution Approach 2:

The patent segments the authentication process into distinct functional units: authentication processing unit that performs the actual authentication, authentication information management unit that stores and manages authentication results, and individual service units that can independently utilize the authentication results. This segmentation allows each component to specialize while working together efficiently.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple types of authentication are combined to improve authentication accuracy, then authentication reliability improves, but the system cannot handle procedures requiring different authentication levels

Engineering Contradiction:
Improveauthentication accuracyVSAvoidauthentication level adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic authentication level adjustment where the system can adaptively select appropriate authentication methods and levels based on the specific service requirements. Different authentication levels can be applied to different services, and the authentication information management unit can provide appropriate authentication results for each service type.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes authentication parameters such as the type of authentication information stored and the level of verification required, depending on the service being accessed. The authentication information management unit can store and retrieve different types of authentication information (face images, voice data, biometric data) based on the specific service requirements.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If users perform personal authentication individually at each institution, then authentication can be completed for each procedure, but excessive user effort and time are required

Engineering Contradiction:
Improveauthentication completionVSAvoidauthentication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary authentication at the first institution, and the authentication result is stored in the authentication information management unit. This preliminary authentication result is then automatically utilized at subsequent institutions, eliminating the need for users to repeat the authentication process at each institution.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The authentication information management unit acts as an intermediary that stores and shares authentication results between different institutions. Instead of direct authentication at each institution, the system uses this intermediary storage unit to efficiently distribute authentication results across multiple services and institutions.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In order to efficiently perform personal authentication when a user performs various procedures, an authentication system causes a user A to access a management device 20 through a mobile terminal 10 and perform initial registration including registration of a moving image of the user A. When the user A uses a service at a branch X of a financial institution ABC or at a convenience store Y, the management device 20 receives a moving image of the user A taken at the branch or store, performs an authentication process corresponding to a usage type, and notifies the branch or store of the authentication result.
