Solution Overview

Problem

Existing access control systems rely on permanently installed devices for hardware tokens and biometric verification, which limits their flexibility and compatibility with mobile devices like smartphones, making it desirable to develop an efficient concept for user access control using mobile communication devices.

Innovation Solution

A mobile communication device equipped with a motion sensor to detect and derive a movement profile, which is transmitted to an access control device for comparison with a predetermined profile, allowing or denying access based on similarity, leveraging behavior-based identification and asymmetric authentication protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If permanently installed devices are used for hardware tokens and biometric verification, then authentication reliability is improved, but device complexity and installation requirements increase

Engineering Contradiction:
Improveauthentication reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mobile communication device is designed to perform multiple functions: it serves as both a communication device and an access control authentication device. The motion sensor, processor, and communication interface in the mobile device enable it to capture movement data, generate movement profiles, and transmit authentication information, replacing the need for separate permanently installed biometric devices and hardware tokens.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system creates a digital copy of the user's movement behavior patterns through movement profiles. The motion sensor captures actual movement data, the processor generates a movement profile that represents the user's behavioral biometrics, and this profile is transmitted to the access control device for verification, replacing physical biometric verification devices.

Inventive Principle:
Principle #26Copying

2Reliability

If permanently installed devices are used for access control, then authentication security is improved, but adaptability to mobile devices deteriorates

Engineering Contradiction:
Improveauthentication securityVSAvoidadaptability to mobile devices
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mobile communication device integrates access control functionality into a universally used device. The motion sensor detects movement, the processor creates movement profiles, and the communication interface transmits authentication data, allowing the mobile device to serve as both a communication tool and a secure access control credential.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system replaces traditional mechanical and physical authentication systems (permanent installations, hardware tokens, biometric scanners) with a software-based movement profile authentication system running on mobile devices. The movement profile data and authentication logic are transmitted digitally, eliminating the need for permanently installed authentication hardware.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If movement profiles are transmitted to access control devices, then ease of operation is improved, but data transmission requirements increase

Engineering Contradiction:
Improveease of operationVSAvoiddata transmission requirements
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system extracts only the essential authentication information from the complete movement data. The motion sensor captures comprehensive movement data, but the processor generates a condensed movement profile that contains only the necessary behavioral biometric features for authentication, transmitting only this extracted essential information to the access control device.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system transforms raw movement data into a different parameter representation through the movement profile. The processor converts complex multi-dimensional movement data into a simplified profile format with key parameters that capture the essential behavioral patterns, reducing data volume while preserving authentication capability.

Inventive Principle:
Principle #35Parameter changes
