Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing technologies lack effective methods to associate iris information with identification information to prevent unauthorized registration and enhance authentication accuracy.

Innovation Solution

An information processing apparatus that outputs a target person code during face information registration or successful face authentication, and registers iris information in association with identification and face information, ensuring only authorized individuals can input the iris information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If iris information is collected and registered without verification, then the registration process is simple and fast, but unauthorized registration can occur and authentication accuracy deteriorates

Engineering Contradiction:

Improveauthentication accuracyVSAvoidregistration process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs face authentication before iris information registration to verify the target person's identity in advance. A target person code is generated and distributed to the authenticated person, who must input this code during iris registration to confirm authorization. This preliminary verification action prevents unauthorized registration while maintaining a relatively simple process flow.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If face authentication is performed before iris registration, then unauthorized registration is prevented, but the registration time and process complexity increase

Engineering Contradiction:

Improveregistration authorizationVSAvoidregistration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system extracts only the essential verification element (target person code) from the face authentication process and uses it for authorization confirmation during iris registration. Instead of requiring the entire face authentication流程 to be repeated, the system extracts and utilizes the authentication result in the form of a code, reducing the time required while maintaining authorization reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If a target person code input system is implemented, then unauthorized iris registration is prevented, but the ease of operation decreases

Engineering Contradiction:

Improveregistration securityVSAvoidiris registration ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables the target person to self-verify their authorization by inputting the target person code they received. This self-service approach allows the person to confirm their own identity and authorization status without requiring additional verification personnel or complex procedures, maintaining ease of operation while ensuring registration security.

Inventive Principle:

Principle #25Self-service

AI summary

An information processing apparatus includes: a code output unit that outputs a target person code to a target person in at least one of a case where face information on the target person is registered and a case where face authentication of the target person is successful; and an iris information registration unit that registers iris information collected from the target person, in association with identification information capable of identifying the target person and the registered face information on the target person, in a case where the target person code is inputted by the target person when registering the iris information on the target person.
