User Identity Verification via Video Phrase Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user identity verification methods on the internet, such as username and password combinations, captchas, and phone number-based systems, lack a reliable means to verify a user's true identity, particularly their appearance.
Innovation Solution
A method involving receiving a request for verification, selecting a phrase associated with a user account, sending it to the user to read aloud in a video recording, and verifying the recorded phrase and appearance against a trusted authority's records, making the video recording accessible to third parties for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional username and password verification is used, then the verification process is simple and quick, but the reliability of identity verification is low and can be easily compromised
Solution Approach 1:
The patent introduces a trusted authority as an intermediary that issues certificates containing biometric templates. This mediator enables third parties to verify user identity without directly accessing sensitive biometric data, thus improving reliability while maintaining system complexity at an acceptable level through standardized verification protocols
Solution Approach 2:
The patent creates a digital copy of the user's biometric characteristics (voice, face, fingerprint) in the form of a template stored in a certificate. This copy allows for reliable verification without requiring the actual physical biometric data, enhancing security and reliability while keeping the verification process manageable
2Reliability
If biometric verification systems are implemented, then the reliability of identity verification improves, but the complexity of the verification system increases
Solution Approach 1:
The patent performs biometric verification in advance by obtaining a video recording during account registration and generating a certificate with the biometric template before actual verification is needed. This preliminary action simplifies the actual verification process, as third parties only need to compare new video recordings against the pre-established template rather than implementing complex real-time analysis
Solution Approach 2:
The system enables users to perform their own verification by recording a video and comparing it against their stored biometric template. This self-service approach simplifies the overall system operation, as users can independently verify their identity without requiring complex centralized verification infrastructure for every authentication event

AI summary
A method for verifying an identity of a user includes (a) receiving a request for an identification phrase from a user associated with a user account; (b) selecting the phrase from a pool of phrases and associating the phrase with the user account; (c) sending the phrase to the user; (d) receiving a video recording showing a person reading one or more phrases aloud, and (e) verifying that a phrase read by the person in the video recording corresponds to the selected phrase. A third party may desire verification of the user's identity. The method confirms to the third party the user's identity based on whether or not the phrase read aloud in the video recording matches the randomly selected phrase associated with the user account.
