Solution Overview

Problem

Existing authentication techniques for accessing applications with sensitive information rely heavily on username-password combinations or biometrics, lacking robustness in determining user presence and maintaining secure access.

Innovation Solution

A computer-implemented method that authenticates a user, establishes a session, and continuously determines user presence using biometric and motion information, maintaining access as long as the user is present and terminating the session if the user is absent for a predetermined duration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If username-password or biometric authentication is used to provide continuous access, then ease of operation is improved, but security reliability deteriorates due to lack of user presence verification

Engineering Contradiction:

Improveaccess continuityVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system continuously monitors user presence through camera-based facial recognition and provides feedback by maintaining or terminating access based on detected presence. The camera captures facial images, compares them against stored biometric data, and dynamically adjusts access permissions accordingly, creating a closed-loop security system.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical authentication systems (username-password entry, static biometric verification) with an automated optical recognition system using facial image capture and processing. This substitution enables continuous, passive verification without requiring active user participation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If continuous authentication monitoring is implemented, then security reliability is improved, but device complexity increases due to additional sensors and processing requirements

Engineering Contradiction:

ImprovesecurityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses the device's existing camera component for multiple purposes: standard photography/video functions and security authentication. By leveraging the camera's dual functionality, the system avoids adding dedicated biometric sensors, thereby reducing overall device complexity while maintaining security capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The authentication system operates autonomously using the device's own camera and processing capabilities without requiring external authentication servers or additional hardware. The device self-verifies user presence through local facial recognition algorithms, reducing system complexity.

Inventive Principle:

Principle #25Self-service

AI summary

A computer-implemented method for managing operation of an application includes: authenticating a user of the application or a user device associated with a user of the application; and establishing a session with the application and enabling access to the application for the user if the user or the user device is authenticated. The method further includes determining, after the user or the user device is authenticated, whether the user or the user device is or remains present. The method further includes maintaining the session and the enabling of access to the application if it is determined that the user or the user device is or remains present; and terminating the session and disabling access to the application if it is determined that the user or the user device is absent for a predetermined duration.
