Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing biometric authentication systems fail to effectively manage user entry and exit by determining appropriate output timing of authentication results based on the difficulty of completing authentication processing, leading to missed alerts for users who exit without completing authentication.

Innovation Solution

An information processing apparatus that acquires biometric information, determines an authentication difficulty degree, and adjusts the output timing of authentication results accordingly, using various determination elements such as user velocity, position, overlap with others, and intent to avoid authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If authentication processing is performed for all users in a batch manner, then processing efficiency is improved, but the timing accuracy for individual authentication results deteriorates

Engineering Contradiction:

Improveauthentication processing efficiencyVSAvoidauthentication result output timing accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts the output timing of authentication results based on individual user characteristics (movement speed, position, authentication difficulty degree) rather than using a fixed batch processing timing. This allows the system to maintain high processing efficiency while achieving accurate timing for each user's authentication result notification.

Inventive Principle:

Principle #15Dynamics

2Reliability

If authentication result is output after complete processing, then authentication accuracy is improved, but users may exit the authentication area without receiving the result

Engineering Contradiction:

Improveauthentication result accuracyVSAvoidauthentication result delivery timing

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by predicting whether a user will exit the authentication area before completing authentication processing. Based on this prediction and the calculated authentication difficulty degree, the system prepares to output results at appropriate timing, ensuring both accuracy and timely delivery before user exit.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from user behavior (movement speed, position changes, time spent in authentication area) to continuously adjust the authentication difficulty degree and determine optimal output timing. This feedback mechanism ensures accurate result delivery while preventing users from exiting without receiving their authentication results.

Inventive Principle:

Principle #23Feedback

3Device complexity

If output timing is fixed for all users, then system simplicity is improved, but authentication result delivery accuracy deteriorates

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system changes multiple parameters (user movement speed, position coordinates, time duration in authentication area, authentication difficulty degree) to dynamically determine output timing. This parameter-based approach maintains relative system simplicity while achieving high timing precision for authentication result delivery.

AI summary

An information processing apparatus includes: an acquisition unit that acquires biometric information on a user located in an authentication area; an authentication unit that performs authentication processing based on the biometric information; an authentication difficulty degree determination unit that determines an authentication difficulty degree indicating a possibility that the user reaches outside the authentication area without completing the authentication processing; and an output timing determination unit that determines output timing of a result of the authentication processing in accordance with the authentication difficulty degree. According to such an information processing apparatus, it is possible to output the authentication result at appropriate timing.
