Secure Media Exchange Kiosk for Malware-Free File Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Removable media, such as USB drives, pose a significant threat to secure networks as they can introduce viruses and malware, serving as a primary vector for cyber-attacks, and existing solutions do not effectively manage the secure exchange of files between protected and unprotected systems.
Innovation Solution
Implementing a Secure Media Exchange (SMX) system on a single board computer, like the RASPBERRY PI, which includes a processing device, touch screen display, and interface for storage devices, to perform check-in and check-out processes. This involves scanning for malware, digitally signing clean files, modifying the file system, and generating results for display, ensuring only trusted devices can access protected systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If removable media are used to transfer information into and out of secure networks, then information exchange capability is improved, but network security deteriorates due to malware introduction risks
Solution Approach 1:
The patent introduces an intermediary system (SMX kiosk with processing device) that mediates between removable media and secure networks. The kiosk performs check-in/check-out processes, scanning for malware and digitally signing files, thereby enabling information exchange while filtering out harmful factors before they can reach the secure network.
Solution Approach 2:
The system performs preliminary actions by scanning removable media for malware and digitally signing clean files before they are allowed to access the secure network. This advance verification prevents malware introduction while maintaining information exchange capability.
2Reliability
If strict security controls are implemented to prevent malware introduction, then network security is improved, but ease of operation deteriorates due to restricted media access
Solution Approach 1:
The system implements self-service through automated check-in and check-out processes. The processing device automatically scans media, identifies malware, digitally signs clean files, and modifies file systems without requiring manual security verification, thereby maintaining strict security controls while improving operational ease.
Solution Approach 2:
Security verification is performed in advance through automated scanning and digital signing processes. This preliminary action establishes trust before media access is granted, allowing strict security controls to be implemented without significantly impacting ease of operation during actual use.
3Reliability
If malware scanning and digital signing processes are implemented, then security reliability is improved, but processing time deteriorates
Solution Approach 1:
The patent replaces manual security verification processes with automated digital signing and scanning mechanisms. The processing device uses cryptographic algorithms for digital signing and automated scanning techniques, substituting time-consuming manual procedures with efficient computational processes that maintain security reliability while reducing processing time.

AI summary
An apparatus includes a single board computer (402) comprising a processing device (302). The apparatus also includes a touch screen display (404) coupled to the single board computer. The apparatus further includes at least one interface (310, 408) configured to be coupled to a storage device (304, 502). The processing device is configured to detect the storage device, perform a check-in process for the storage device, and generate a result of the check-in process for display on the touch screen display. To perform the check-in process, the processing device is configured to scan the storage device to identify any malware contained on the storage device, digitally sign one or more clean files on the storage device, and modify a file system of the storage device.
