Avatar Identity Verification via Biometric Feature Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques lack effective methods for verifying user identities during computer-mediated interactions, allowing nefarious users to impersonate others by controlling avatars, which compromises security and trust.
Innovation Solution
A computer-implemented method that generates features from video and audio data during interactions and compares them with known user features to verify identity, using fingerprint generation and matching to ensure authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If avatars are used to represent users in computer-mediated interactions, then user privacy and control are improved, but user identity verification capability deteriorates
Solution Approach 1:
The patent introduces an intermediary identity verification system that operates between the user and the avatar. This system extracts biometric features from video and audio data, generates identity fingerprints, and verifies user identities without exposing raw biometric data. The intermediary layer maintains privacy while enabling verification by processing data through encrypted feature extraction and comparison mechanisms.
Solution Approach 2:
The patent extracts essential identity verification elements (biometric features) from the complete video and audio data streams. By taking out only the necessary fingerprint features for verification while leaving the rest of the personal data protected, the system achieves both privacy protection and identity verification capability.
2Adaptability or versatility
If avatars control user interactions remotely, then interaction flexibility is improved, but security against impersonation deteriorates
Solution Approach 1:
The patent implements preliminary identity verification by extracting and comparing biometric features before allowing avatar control. The system performs fingerprint generation and matching in advance to authenticate users, preventing impersonation before it can occur. This preliminary security check maintains interaction flexibility while blocking harmful impersonation attempts.
3Reliability
If direct user video and audio sharing is replaced with avatars, then user control over personal data is improved, but trust verification capability deteriorates
Solution Approach 1:
The patent replaces the mechanical system of direct video/audio sharing with an automated biometric verification system. Instead of manually sharing personal data, the system automatically extracts features, generates fingerprints, and verifies identities through computational processes. This substitution maintains user control over data while restoring trust verification capability through automated authentication.

AI summary
Techniques are disclosed herein for verifying user identities. The techniques include generating one or more features based on at least one of video data or audio data generated during a computer-mediated interaction between a plurality of users in which a first user included in the plurality of users is represented by an avatar, and verifying an identity of the first user based on the one or more features that are generated and one or more features associated with the first user.
