Solution Overview

Problem

Existing biometric authentication systems face challenges in preventing user errors during the authentication process, which can lead to unsuccessful authentication and increased vulnerability to impersonation attempts, as users are often unaware of the specific biometric data required for authentication.

Innovation Solution

A biometric data processing system that guides users through a series of actions by displaying messages and illustrations, requesting specific biometric features, and continuously detecting predetermined actions, ensuring that the input biometric data meets quality standards and matches previously registered data, thereby preventing unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric data acquisition and collation time is extended to ensure high security and high-resolution data processing, then authentication reliability is improved, but the window for potential erroneous user operation increases

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidauthentication process time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system displays guidance information to users before the authentication process begins, indicating what biometric data will be required and how to provide it. This preliminary action prepares users in advance, reducing the likelihood of erroneous operations during the authentication process while maintaining sufficient time for high-resolution biometric data acquisition and collation.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If users are provided with detailed guidance on biometric data input during authentication, then ease of operation is improved, but information security may be compromised by revealing authentication requirements

Engineering Contradiction:
Improveuser operation easeVSAvoidauthentication information security
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system provides guidance information in advance that describes the authentication process and required user actions without revealing specific security-critical details. This allows users to understand what to do during authentication while maintaining the security of the actual authentication requirements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guidance information acts as an intermediary between the authentication system and the user. It provides necessary operational instructions while filtering out security-critical information, allowing users to perform actions correctly without having access to sensitive authentication details that could be exploited by impersonators.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the authentication system requires users to follow specific instructed actions, then resistance to impersonation is improved, but device complexity increases

Engineering Contradiction:
Improveimpersonation resistanceVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system prepares and displays guidance information before authentication begins, clearly indicating the specific actions users need to perform. This preliminary instruction reduces the complexity of the authentication process by pre-establishing the expected user behavior, making it easier for users to follow and harder for impersonators to replicate without knowing the specific instructions.

Inventive Principle:
Principle #10Preliminary action

AI summary

A biometric data processing apparatus (500) includes a control unit (50) that displays, on a display unit, a message requesting the user to perform a predetermined action, and an authentication unit (52), wherein in a case where a first score calculated by collating biometric data of the user with previously-registered biometric data is equal to or more than a predetermined threshold value and a detection unit continuously detects a predetermined action from when the detection unit first detects the predetermined action after the message is displayed until an authentication process in the biometric data processing apparatus is ended, the authentication unit (52) determines that authentication of the user is successful.
