Data Card Security via Dual Password Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data cards lack security measures, allowing easy copying of information from network terminals, leading to potential data leaks and loss for enterprises.
Innovation Solution
A data card application method and device that determines the usage state of a memory card during initialization and modifies configuration information only when consistent modification passwords are provided twice, enabling or disabling the card's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data card allows easy access to memory card without restrictions, then ease of operation is improved, but security of enterprise information deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by pre-configuring usage state restrictions and password protection mechanisms in the data card before any data access occurs. The control unit is programmed to automatically enforce these restrictions, preventing unauthorized copying operations before they can compromise enterprise information security.
Solution Approach 2:
The patent introduces a control unit as an intermediary between the memory card and the terminal device. This control unit acts as a security gatekeeper that mediates all access requests, verifying usage states and password credentials before allowing any data operations, thus protecting enterprise information while maintaining controlled accessibility.
2Object-affected harmful factors
If data card implements password verification and usage state restrictions, then security of enterprise information is improved, but device complexity increases
Solution Approach 1:
The control unit is designed with multi-functionality, serving both as a security management module (enforcing usage states, verifying passwords) and as a general data access controller. This universal component handles multiple security-related tasks within a single integrated unit, avoiding the need for separate dedicated security hardware and thereby limiting the increase in device complexity.
3Reliability
If data card implements modification password verification, then reliability of configuration information is improved, but ease of operation deteriorates
Solution Approach 1:
The system requires preliminary password verification actions to be completed before any configuration modification can occur. The control unit is pre-programmed to demand password authentication in advance of any configuration changes, ensuring that only authorized users can modify settings. This preliminary security check guarantees the reliability of configuration information while introducing an additional operational step.

AI summary
Provided are a data card application method and a data card. The data card application method includes: after a data card is connected to a terminal and a memory card is inserted into the data card, determining a usage state of the memory card during initialization of the data card; when the usage state of the memory card is modified, modifying configuration information in the data card when modification passwords acquired twice are consistent; and re-determining the usage state of the memory card according to the modified configuration information, and performing a corresponding operation on the memory card according to the re-determined usage state. By means of the method, restrictions are placed for memory cards using the data card, thereby improving the security of internal information of an enterprise.
