Biometric Authentication Forgery Detection and Network Notification

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional biometrics authentication techniques fail to immediately detect and address illegal authentication attempts, especially in environments without network connectivity, allowing malicious users to repeatedly attempt forgery without notification to administrators.

Innovation Solution

An authentication method that involves a first program executing a predetermined process without network connectivity and a second program with network connectivity, where forgery detection information is stored and notified to a server upon invocation of the second program, enabling immediate detection and notification of illegal authentication attempts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometrics authentication is performed in a program without network connection function (first program), then authentication can be performed in isolated environments, but forgery detection results cannot be immediately notified to administrators

Engineering Contradiction:

Improveauthentication securityVSAvoidnotification delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent stores forgery detection results in storage means during the first authentication process, preparing the information in advance so that it can be immediately notified when network connectivity becomes available. This preliminary storage action resolves the contradiction by ensuring security monitoring occurs even when immediate notification is impossible.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a second program with network connection function that acts as an intermediary between the first program (without network) and the notification system. This intermediary receives and forwards authentication results, enabling notification capability to be added without modifying the core authentication process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If log notification is delayed until the next authentication is successfully performed, then network connectivity requirements are reduced, but illegal users can repeatedly attempt forgery without detection

Engineering Contradiction:

Improveenvironment flexibilityVSAvoidillegal access prevention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary storage of authentication results in the first program, ensuring that forgery detection data is captured immediately regardless of network status. This preliminary action maintains reliability by preventing data loss while allowing the system to adapt to environments where immediate notification is not possible.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent establishes a feedback mechanism where authentication results are stored and then notified to administrators once network connectivity is available. This feedback loop ensures that security monitoring is continuous and that administrators are informed of illegal attempts as soon as possible, maintaining reliability while adapting to network constraints.

Inventive Principle:

Principle #23Feedback

3Loss of information

If a second program with network connection function is invoked after the first program, then forgery detection results can be notified to servers, but system complexity increases

Engineering Contradiction:

Improveforgery detection notificationVSAvoidprogram structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The second program is designed to serve multiple functions: it provides network connectivity for notification, performs user authentication, and manages the transmission of stored authentication results. This multi-functionality reduces overall system complexity by consolidating multiple roles into a single program rather than requiring separate specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An authentication method for use in an apparatus having a function, a function to execute a first program that executes a predetermined process after first user authentication with biometrics authentication is performed and does not have a network connection function, and a function to execute a second program that is invoked after the first program is executed, executed after second user authentication and has a network connection function comprises executing the first program in forgery detection mode regardless of a result of a user determination if biometrics authentication with forgery is detected at the time of the first user authentication, invoking the second program in the forgery detection mode after the first program is executed in the forgery detection mode, and notifying a device connected to an external network of forgery detection information by using the network connection function after the second program is invoked in the forgery detection mode.
