Solution Overview

Problem

Current virtual platforms lack effective methods to verify the identity and active participation of users, allowing unauthorized individuals or bots to hijack user profiles and avatars, compromising the integrity of virtual environments.

Innovation Solution

Implement biometric data authentication to verify user identity and active participation, animating avatar features based on real-time biometric data to indicate verified status, using predefined thresholds for biometric data comparison.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric data authentication is implemented to verify user identity and active participation, then security and reliability are improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Improveuser identity verificationVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical authentication methods (passwords, security questions) with biometric authentication systems that use physiological or behavioral characteristics (fingerprint, facial recognition, voice patterns, gait analysis). This substitution provides more reliable identity verification while the automated nature of biometric processing minimizes the perceived complexity for users.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces biometric data as an intermediary element between the user and the virtual environment. Instead of directly verifying identity through complex security protocols, the system uses biometric characteristics as a mediator that automatically confirms user identity and active participation, simplifying the authentication process while enhancing security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If biometric data authentication is implemented to verify user identity, then security is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveuser identity verificationVSAvoidauthentication process simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements self-service biometric authentication where the system automatically captures, processes, and verifies biometric data without requiring active user intervention beyond initial enrollment. The biometric sensors automatically detect and process characteristics (fingerprint, face, voice) as the user naturally interacts with the device, making the process as simple as traditional login while providing superior security.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual authentication actions (typing passwords, answering security questions) with automated biometric recognition processes. This substitution eliminates the need for users to remember complex credentials or perform deliberate authentication actions, thereby improving ease of operation while enhancing security through more reliable identity verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If avatar animation is used to indicate verified status, then information transmission is improved, but device complexity deteriorates

Engineering Contradiction:

Improveuser verification status communicationVSAvoidavatar animation system complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses color changes in avatar indicators (such as changing the color of an avatar's border, aura, or specific features) to communicate verification status. For example, a green border indicates verified status while red indicates unverified. This visual coding system efficiently transmits information about user authentication state without requiring complex animation sequences or additional interface elements.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent applies partial animation to specific avatar features rather than animating the entire avatar. For example, only the avatar's eyes blink, or a small indicator icon appears near the avatar, rather than full-body animations. This selective approach provides sufficient information about verification status while minimizing the computational resources and complexity required for the animation system.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The various implementations described herein include methods for authenticating user participation in a virtual environment. In one aspect, a method is performed for a platform that includes an avatar representing a user. The method includes receiving biometric data for the user and comparing the received biometric data to stored biometric data for the user according to a predefined threshold. The method also includes, when the received biometric data falls within the predefined threshold in comparison to the stored biometric data, animating features of the avatar according to the received biometric data. The method further includes, in response to a determination that the received biometric data does not fall within the predefined threshold in comparison to the stored biometric data, ceasing animation of the features of the avatar. Animation of the features of the avatar indicates that the user is actively engaged on the platform.
