Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In virtual spaces, there is a lack of appropriate entry/exit management for specific regions, as it is unclear whether an avatar is operated by its associated user, leading to potential unauthorized access.

Innovation Solution

An information processing device that receives setting information for restricting entry to a partial virtual space region, performs biometric authentication of the user operating an avatar attempting to enter the region, and determines whether to allow entry based on the authentication results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric authentication is performed for avatar entry to specific regions, then security and access control are improved, but system complexity and processing time increase

Engineering Contradiction:

Improveentry/exit management reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an information processing device as an intermediary between the avatar and the specific region. This device performs biometric authentication by comparing the user's biometric information with registered data, acting as a mediator that verifies identity before allowing avatar entry into restricted regions, thereby improving security without requiring direct complex integration into the virtual space infrastructure

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs biometric authentication in advance before the avatar is allowed to enter the specific region. By conducting the authentication check beforehand and determining entry permission prior to actual entry, the system ensures security requirements are met while streamlining the entry process

Inventive Principle:

Principle #10Preliminary action

2Reliability

If biometric authentication is performed for avatar entry to specific regions, then access control accuracy is improved, but processing time increases

Engineering Contradiction:

Improveaccess control accuracyVSAvoidauthentication processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The information processing device performs biometric authentication in advance before avatar entry is permitted. By determining entry permission beforehand through automated biometric comparison, the system ensures accurate access control while enabling smooth entry once authentication is complete, reducing actual entry delay

Inventive Principle:

Principle #10Preliminary action

AI summary

One of the purposes of the present invention is to provide an information processing device which is capable of performing appropriate entry/exit management with respect to an arbitrary region in a virtual space. An information processing device according to one embodiment of this disclosure comprises: a reception means for receiving input of setting information indicating a region of a virtual space; a region control means for setting, as a specific region, the region of the virtual space indicated in the setting information; an authentication means for performing biometric authentication of a user that operates an avatar, if the avatar is to enter the specific region; and a determination means for determining whether to permit entry of the avatar into the specific region, according to results of the biometric authentication.
