Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In continuous authentication systems, including gait authentication, there is a risk of false rejection, leading to impaired user experience when the authentication fails without prior notification.

Innovation Solution

An information processing device and method that acquire a trigger point before a predetermined operation on a control target, perform continuous authentication based on motion information, and notify the user of authentication failure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If continuous authentication is performed using motion information, then user convenience is improved, but false rejection rate increases leading to user experience impairment

Engineering Contradiction:

Improveuser convenienceVSAvoidfalse rejection rate

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs continuous authentication in advance before the user attempts to operate the control target. By acquiring a trigger point that is passed before the operation point and executing authentication at this earlier stage, the system proactively identifies authentication failures before they impact user operations, allowing for timely notifications and alternative authentication methods

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback mechanism by notifying the user of authentication failure results in real-time. When the continuous authentication unit determines that authentication has failed, the notification unit immediately informs the user, enabling them to take corrective actions such as attempting alternative authentication methods before proceeding with control target operations

Inventive Principle:

Principle #23Feedback

2Device complexity

If authentication is performed only at the operation point, then system simplicity is maintained, but user experience is impaired due to late failure detection

Engineering Contradiction:

Improvesystem simplicityVSAvoiduser experience timing

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The system introduces a trigger point that is acquired in advance before the operation point. This trigger point serves as an early authentication checkpoint, allowing the system to perform authentication ahead of time without significantly complicating the overall system architecture. The trigger point is determined based on position information or operation sequence, making the early authentication seamless into the existing workflow

AI summary

An information processing terminal 10 includes: a trigger point recording unit 118 that acquires a trigger point at which gait authentication of a user for unlocking doors is performed, the trigger point passed through before a point at which unlocking the doors is performed on the vehicle 30; a gait authentication unit 140 that performs the gait authentication on a basis of motion information obtained by continuously measuring walking of the user when the trigger point is passed; and an information presentation unit 134 that notifies the user that the gait authentication has failed in a case where the gait authentication has failed.
