Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems fail to ensure the identity of a user acting in both a virtual space and a real space, necessary for granting benefits in the real world in response to actions in the virtual space.

Innovation Solution

A system comprising a regional application server, a metaverse server, and an authentication server that uses biometric information to authenticate users and issue certificates for benefits enjoyed in the real world, ensuring the same identity across both spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a system associates user actions in virtual space with actions in real space to enable benefit granting, then the functionality and versatility of the system is improved, but the reliability and security of identity verification deteriorates because no authentication mechanism is implemented

Engineering Contradiction:

Improvebenefit granting functionalityVSAvoididentity verification

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an authentication server as an intermediary component between the virtual space platform and the real space benefit granting system. This authentication server verifies user identities through biometric authentication and issues authentication results that bridge the virtual and real spaces, ensuring that the same individual acts in both spaces. The intermediary resolves the contradiction by adding a reliable verification layer without preventing the cross-space benefit granting functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If biometric authentication is implemented to ensure user identity across virtual and real spaces, then the reliability and security of the system is improved, but the device complexity and system architecture deteriorates due to additional authentication server and certificate management

Engineering Contradiction:

Improveidentity verificationVSAvoidsystem architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the system into distinct functional modules: a virtual space platform, an authentication server, and a real space benefit granting system. Each module has a specific responsibility - the virtual space platform handles user actions, the authentication server handles identity verification and certificate issuance, and the benefit granting system handles real space benefits. This segmentation reduces overall system complexity by creating clear boundaries and responsibilities for each component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The authentication server performs multiple functions: it authenticates users from the virtual space, verifies their identities for real space benefit granting, issues authentication certificates, and manages the linkage between virtual and real space identities. This multi-functionality reduces the need for separate specialized components, thereby managing system complexity while maintaining high reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If a certificate system is introduced to verify user identity for benefit provision, then the measurement precision of user identity is improved, but the loss of time increases due to additional authentication and verification steps

Engineering Contradiction:

Improveuser identity verificationVSAvoidauthentication time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary authentication where user biometric data is captured and verified in advance before the user needs to claim benefits in the real space. The authentication server issues an authentication certificate that proves the user's identity has already been verified. This preliminary action eliminates the need for repeated authentication during benefit claiming, reducing time loss while maintaining high identity verification precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The authentication certificate acts as a copy or representation of the user's verified identity. Instead of requiring the original biometric verification process each time benefits are claimed, the system uses the certificate copy to prove identity. This copying mechanism maintains measurement precision of identity verification while significantly reducing the time required for subsequent verification steps.

Inventive Principle:

Principle #26Copying

AI summary

A system includes a regional application server, a metaverse server, and an authentication server. The authentication server authenticates a user who attempts to log in to the regional application server and the metaverse server. In a case where the user determined to have succeeded in the authentication experiences content related to the predetermined region, the metaverse server grants a benefit that can be enjoyed in the predetermined region to the user who experienced the content and issues a certificate of the granted benefit. In a case where the user determined to have succeeded in the authentication desires to enjoy the granted benefit, the regional application server acquires the certificate of the granted benefit and performs control related to a provision of the benefit by using the acquired certificate.
