Textile Machine Access Control Using Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control systems for textile machines are cumbersome and time-consuming, relying on manual entry of user names and passwords, which can lead to unauthorized access and inefficient management of access rights.
Innovation Solution
A system utilizing a sensor unit and authentication system across two communication networks to authenticate users using existing identification means, such as biometric features, and an interface for secure communication between the textile machine and authentication system, enabling efficient and secure access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual user name and password entry is used for access control, then access protection is provided, but user identification becomes time-consuming and complex
Solution Approach 1:
The patent replaces the mechanical manual entry system with an automated optical recognition system. A camera captures images of the user's face or other biometric features, and image processing algorithms automatically identify and authenticate the user, eliminating the need for manual typing of usernames and passwords.
Solution Approach 2:
The system enables self-service authentication where users present their biometric features (such as face) for automatic recognition and identification. The system autonomously performs the authentication process without requiring manual intervention, thus reducing time loss while maintaining security.
2Reliability
If manual access right management is implemented on each individual machine, then access control is enforced, but administration becomes complicated and time-consuming
Solution Approach 1:
The patent implements a centralized authentication server that serves multiple machines across the network. This single server handles authentication for all connected devices, providing universal access control functionality. Administrators can manage user credentials and access rights from one central location rather than configuring each machine individually, significantly reducing administrative complexity while maintaining control enforcement.
3Device complexity
If centralized authentication system is implemented across the network, then access right administration is simplified, but network dependency increases
Solution Approach 1:
The authentication server implements backup mechanisms and redundancy measures to cushion against potential failures. This may include backup servers, failover mechanisms, or cached authentication data that allows the system to continue operating even if the primary authentication server becomes unavailable, thus maintaining reliability while benefiting from centralized management.
