Microexpression Analysis for Multi-Factor Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information security and user authentication technologies fail to reliably detect unauthorized access attempts and effectively leverage microexpressions for user identification and media presentation customization.
Innovation Solution
A system that captures and processes microexpressions to establish baseline features for user verification in multi-factor authentication and sentiment analysis for media presentation customization, using training and test media items to authenticate users and adjust content based on user sentiments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If login credentials validation is used for user verification, then user authentication can be performed, but the system can be compromised by third parties through cyberattacks
Solution Approach 1:
The patent segments authentication into multiple independent factors: something you know (credentials), something you have (device), and something you are (microexpressions). This segmentation ensures that compromise of one factor does not lead to complete system failure, as the microexpression biometric layer provides an additional security barrier that is difficult to replicate or steal.
Solution Approach 2:
The patent introduces microexpression analysis as an intermediary verification layer between the user and the system. This intermediary captures involuntary facial muscle movements that occur naturally when users view specific media content, creating a biometric signature that mediates the authentication process and cannot be easily replicated by attackers.
2Ease of operation
If static media items are displayed for all users, then media presentation can be simplified, but media presentation customization cannot be achieved
Solution Approach 1:
The patent performs preliminary action by capturing and analyzing user microexpressions during an initial authentication interaction with media content. This preliminary analysis establishes a baseline of the user's authentic emotional responses to different media types, which is stored and later used to automatically customize media presentations without requiring complex real-time processing during subsequent interactions.
Solution Approach 2:
The patent implements feedback by using captured microexpression data to automatically adjust and personalize media presentations. The system analyzes the user's involuntary facial responses to media content and uses this feedback to customize future media recommendations and presentations, creating a dynamic adaptation loop that continuously improves personalization while maintaining system simplicity.

AI summary
A system for identifying a user using microexpressions presents training media items to the user. The system captures a first set of microexpressions of the user in reaction to the training media items. The system, based on the first set of microexpressions, determines baseline features indicating reactions of the user to the training media items. The system presents test media items to a person. The system captures a second set of microexpressions of the person in reaction to the test media items. The system, based on the second set of microexpressions, determines test features indicating reactions of the person to the test media items. The system determines whether the person is the same as the user by comparing the baseline features to the test features. The system determines that the person is the same as the user if the test features correspond to the baseline features.
