USB Link Lock Device with Blocking Member and Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The widespread use of USB ports in computers has made it easy for unauthorized access and virus infections, leading to data loss and information theft, as third parties can easily connect USB memory devices, necessitating a solution to physically block USB ports and prevent unauthorized access.
Innovation Solution
A USB link lock device with a blocking member that inserts into a USB port, a locking mechanism to prevent removal, and a stopping member to block unauthorized USB connections, along with a signal connection for authorized access, ensuring only pre-authorized devices can connect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If USB ports are made universally accessible for easy device connection, then ease of operation is improved, but security against unauthorized access and virus infection deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-authorizing specific USB devices before they can connect to the system. The authorization process occurs in advance through a registration mechanism that stores authorized device information in a database, so that when connection attempts are made, only pre-approved devices are permitted to access the system, preventing unauthorized access and virus infections while maintaining ease of operation for authorized devices
2Object-affected harmful factors
If physical blocking of USB ports is implemented to prevent unauthorized access, then security is improved, but ease of operation for authorized devices deteriorates
Solution Approach 1:
The patent introduces an intermediary authorization system that mediates between the physical USB port and the computer system. This intermediary mechanism includes an authorization database that stores information about approved USB devices, a detection unit that identifies connected devices, and a control unit that permits or blocks access based on authorization status. This intermediary layer enables automatic verification without requiring manual intervention, thus maintaining ease of operation while preventing unauthorized access
3Reliability
If USB device authorization and blocking mechanisms are implemented, then security against information theft is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the system to automatically manage USB device authorization without requiring continuous manual intervention. The authorization database automatically stores and retrieves device information, the detection unit automatically identifies connected devices, and the control unit automatically permits or blocks access based on pre-stored authorization data. This self-service mechanism reduces the need for complex manual control systems while maintaining high security standards
