Mobile Access Control System with Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric locks using RFID technology cannot identify the holder of the induction card, leading to unauthorized access if the card is lost, as anyone can use the card to access the lock.
Innovation Solution
A control system that includes a controller connected to a control device, user mobile devices, and a manager mobile device, utilizing wireless transmission modules and input devices for identification information, such as facial images, fingerprints, or vocal prints, to authenticate users and manage access permissions, ensuring the lock remains locked if the card is lost or stolen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID induction card technology is used for access control, then access speed and convenience are improved, but security deteriorates because the system cannot identify the card holder and allows unauthorized access if the card is lost
Solution Approach 1:
The access control system is segmented into multiple authentication layers: RFID card authentication provides quick access, while facial recognition authentication provides security verification. Both layers must work together, so losing the card only disables one layer of access, not the entire system.
Solution Approach 2:
The system introduces a biometric authentication intermediary (facial recognition) between the RFID card and the locking mechanism. Even if someone has the RFID card, they must also pass the biometric verification to access the lock, preventing unauthorized access.
2Reliability
If conventional mechanical locks with keys are used, then security is maintained through physical control, but convenience deteriorates as users must carry multiple keys and remember corresponding locks
Solution Approach 1:
The system replaces the mechanical key-lock system with an electronic access control system using RFID cards and biometric authentication. This eliminates the need for physical keys and manual locking mechanisms, providing both security and convenience through automated electronic verification.
3Ease of operation
If RFID cards are used for access control, then ease of operation is improved, but loss of information worsens because the system cannot track or identify the card holder when the card is lost or stolen
Solution Approach 1:
The system implements feedback through biometric verification that confirms the identity of the person attempting access. The facial recognition system provides feedback about the card holder's identity, allowing the system to track and verify who is actually using the access card, preventing misuse by unauthorized persons.

AI summary
A control system includes a control device, a controller, a plurality of user mobile devices, and a manager mobile device. Initial first identification information picked up by each user mobile device is sent to the manager mobile device, is authenticated, and is encoded. Every time a user mobile device is connected to the controller for opening the control device, a holder of the user mobile device is requested to input an instant first identification information. After decoding by a decoding key, the controller identifies whether the instant first identification information is identical to the authenticated initial first identification information. The identification result is used to decide whether the control device should be set to be an open state.
