Card-Number NFC Authentication for Display Device Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teaching devices lack identity authentication systems, leading to unauthorized operation, damage, and management difficulties due to unmanaged user access.
Innovation Solution
A display device and system that uses a card number signal for identity verification, generating a near-field communication connection to unlock the device after successful verification, managed by a cloud server with encryption and time-limited verification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no identity authentication system is equipped, then the device is easy to operate and access, but unauthorized users can operate the device leading to management difficulties and potential damage
Solution Approach 1:
The patent introduces an identity authentication module as an intermediary component between the user and the display device. This module verifies user identities through card numbers and generates corresponding user data, acting as a mediator that controls access without requiring complex system changes to the display device itself. The authentication module serves as a standalone intermediary that manages user verification and data distribution.
Solution Approach 2:
The system is segmented into distinct functional modules: an identity authentication module that handles verification, a user data management module that stores and distributes data, and the display device itself. This segmentation allows the authentication functionality to be added independently without redesigning the entire system, reducing overall complexity while improving security.
2Object-affected harmful factors
If identity authentication is implemented, then unauthorized access is prevented, but the operation process becomes more complex and time-consuming
Solution Approach 1:
User identities and corresponding user data are pre-configured in the system before actual use. When a user presents their card number, the authentication module simply matches it against pre-stored information and retrieves the corresponding pre-prepared user data. This preliminary preparation eliminates the need for complex real-time verification processes, making the actual operation quick and convenient while maintaining security.
Solution Approach 2:
The system uses card numbers as simplified copies or representations of user identities, rather than requiring verification of actual physical identification documents. The card number serves as a digital copy that uniquely identifies the user and triggers retrieval of their associated user data, greatly simplifying the authentication process while maintaining authorization integrity.
3Ease of repair
If user identities are not managed, then the device can be freely accessed, but the device may be damaged and maintenance becomes difficult
Solution Approach 1:
The system implements feedback by recording which user data corresponds to which card number and user identity. When maintenance or damage occurs, the system can trace back which user operated the device by examining the user data in use. This feedback mechanism provides accountability and helps maintenance personnel identify potential issues related to specific users without requiring complex monitoring systems.
