Mobile Device Control System for Secure Access Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mechanical locks require multiple keys and do not securely identify the user, allowing unauthorized access if the induction card is lost or stolen, as they only verify the card's identity rather than the card holder's.
Innovation Solution
A control system using mobile devices with a controller, main memory, and wireless transmission devices, where users and managers input identification information, and encoded information is used to authenticate and authorize access, ensuring the lock remains locked unless the correct user is present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID induction card is used for access control, then user identification is simplified and access is convenient, but security is compromised because the card cannot identify its holder allowing unauthorized access if lost or stolen
Solution Approach 1:
The system segments the identification process into two distinct parts: the static RFID card containing identification data, and the dynamic biometric verification (fingerprint, facial recognition, or iris scan) that confirms the holder's identity. This segmentation ensures that even if the card is lost, unauthorized access is prevented because the biometric characteristics cannot be replicated.
Solution Approach 2:
The control device acts as an intermediary between the RFID card and the access decision. It receives both the card identification number and biometric data, verifies their correspondence, and only then grants access. This intermediary role ensures that the card alone is insufficient for access, combining it with biometric verification to maintain security.
2Reliability
If multiple keys are required for different mechanical locks, then each lock can be securely controlled, but carrying and remembering keys becomes inconvenient
Solution Approach 1:
The mobile device serves multiple functions: it stores RFID card data for identification, captures biometric data for verification, communicates with the control device via wireless transmission, and can even remotely manage access permissions. This multi-functionality replaces the need for multiple physical keys and simplifies key management while maintaining security.
Solution Approach 2:
The system replaces mechanical key-lock systems with an electronic control system. Instead of inserting physical keys into mechanical locks, users present their mobile device, and the control device electronically verifies identity through RFID and biometric matching, then actuates the lock mechanism. This substitution eliminates the inconvenience of carrying and managing multiple physical keys.
3Extent of automation
If conventional mechanical locks with electrical identity identification are used, then locking and unlocking can be controlled electronically, but the system cannot identify the actual holder of the identification card
Solution Approach 1:
The system performs preliminary biometric verification before granting access. The mobile device captures the user's biometric data (fingerprint, facial image, or iris pattern) and sends it to the control device for verification against stored data. This preliminary action ensures that the actual holder is identified before the lock is actuated, preventing unauthorized access even if the RFID card is compromised.
Solution Approach 2:
The control device provides feedback by comparing the received biometric data with stored reference data and notifying the user of the verification result. If the biometric characteristics match the registered data, access is granted; otherwise, access is denied. This feedback mechanism ensures accurate identity verification and maintains system security.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system securely authenticates users and prevents unauthorized access by ensuring the lock is only opened with the correct user's identification information, even if the mobile device is lost or stolen, enhancing security and convenience.

AI summary
A control system includes a control device, a controller, a plurality of user mobile devices, and a manager mobile device. An initial first identification information picked up by each user mobile device is sent to the manager mobile device, is authenticated, and is encoded together with a control device identification number corresponding to the control device. 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 and identifies whether the obtained control device identification number is identical to that of the control device. The identification result is used to decide whether the control device should be set to be an open state.
