Solution Overview

Problem

Existing authentication devices take time to authenticate users as they compare biometric information in a fixed order, which can delay the authentication process.

Innovation Solution

An authentication device that prioritizes the comparison of biometric information based on the user associated with the terminal from which identification information is received, reducing the time taken for successful authentication by optimizing the comparison order.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If biometric information is compared in a predetermined fixed order, then the authentication process is systematic and straightforward, but the time taken for successful authentication increases

Engineering Contradiction:
Improveauthentication speedVSAvoidauthentication time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the comparison order changeable based on terminal identification information. Instead of a fixed predetermined order, the system dynamically adjusts the comparison sequence according to which terminal is present, prioritizing users associated with detected terminals to reduce authentication time while maintaining systematics through rule-based adjustment

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies preliminary action by acquiring terminal identification information before the biometric comparison process begins. This allows the system to pre-determine the optimal comparison order based on which terminals are present, so that when authentication starts, the comparisons are already optimized for the specific situation, reducing overall authentication time

Inventive Principle:
Principle #10Preliminary action

AI summary

An authentication device (10; 20) that authenticates a user using person specifiable information includes a first storage unit (13) configured to store person specifiable information specifying a registered user, a second storage unit (14) configured to store association information in which the registered user is associated with a predetermined terminal (40) possessed by the registered user, a first acquisition unit (11) configured to acquire person specifiable information from an authentication target user, a second acquisition unit (12) configured to acquire identification information, a user specifying unit (15; 25) configured to specify a user associated with the terminal (40) transmitting the identification information based on the association information and the identification information, and an authentication processing unit (16; 26) configured to authenticate the authentication target user by executing a comparison process between the person specifiable information of the authentication target user and the person specifiable information of the registered user in an order that is set based on the specified user.
