Solution Overview

Problem

Existing authentication methods in e-commerce are vulnerable to identity theft, identity fraud, spoofing, and phishing, particularly in online transactions, where verifying the liveliness of biometric data is challenging to prevent unauthorized access.

Innovation Solution

Implementing computer-implemented methods that analyze real-time corneal reflections and face pose changes to determine facial liveliness, using camera devices and sensors to capture and process images, and comparing these changes to predetermined motion patterns or illumination changes to authenticate users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods are used, then ease of operation is improved, but reliability deteriorates due to vulnerability to identity theft and spoofing

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The authentication system is segmented into multiple independent verification components: corneal reflection analysis, face pose estimation, and motion pattern recognition. Each component processes specific aspects of facial data separately, then combines results to achieve comprehensive liveness detection, improving reliability without requiring a single complex authentication mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary liveness detection layer between traditional authentication and the user. This intermediary analyzes corneal reflections and motion patterns to verify authenticity before allowing access, acting as a mediator that enhances security while maintaining the underlying authentication framework

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple verification parameters are analyzed, then measurement precision is improved, but loss of time increases due to processing requirements

Engineering Contradiction:
Improveliveness detection precisionVSAvoidauthentication time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of corneal reflection positions and face pose estimates during the image capture phase. By pre-processing these parameters before final liveness determination, the system reduces the computational burden during the authentication decision phase, maintaining high precision while minimizing time loss

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The authentication system continuously captures and analyzes facial data across multiple sequential images. This continuous analysis of corneal reflections and motion patterns allows the system to accumulate verification evidence over time, improving measurement precision through multiple measurements while distributing the processing load to reduce overall authentication time

Inventive Principle:
Principle #20Continuity of useful action
