Erasing Device for Secure Data Transfer via Virus Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively prevent virus infection from large-capacity storage devices to information processing devices, especially when devices are not simultaneously connected, and cannot handle unknown viruses or non-executable file formats.
Innovation Solution
An erasing device with a first connector for the storage device and a second connector for the information processing device, featuring a data eraser and an access controller that erases data stored in the storage device when both are connected, and an abnormality notifier for failed erasure, allowing secure transfer of information between remote devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is erased from the storage device when connected to an information processing device, then virus infection is prevented, but data loss occurs
Solution Approach 1:
The system performs preliminary identification of the storage device's usage state before executing data erasure. By detecting connection patterns and usage history in advance, the system determines whether the storage device is in a virus-prone state (requiring erasure) or a normal usage state (preserving data), thus preventing unnecessary data loss while maintaining virus protection
Solution Approach 2:
The system continuously monitors the connection state between the storage device and information processing devices, using this feedback to dynamically adjust the virus protection strategy. Based on real-time connection information and usage patterns, the system decides whether to activate data erasure, thereby avoiding data loss in normal scenarios while maintaining protection when needed
2Adaptability or versatility
If the storage device is connected to multiple information processing devices sequentially, then data transfer between remote devices is enabled, but virus infection risk increases
Solution Approach 1:
Before the storage device connects to a new information processing device, the system preliminarily analyzes the connection history and usage state to assess virus risk. This preliminary assessment enables the system to prepare appropriate protection measures in advance, allowing safe data transfer while preventing virus infection
Solution Approach 2:
The system acts as an intermediary between the storage device and information processing devices, monitoring and controlling the interaction. By mediating the connection and data transfer process, the system enables versatile data transfer between remote devices while simultaneously protecting against virus infection through continuous state monitoring
3Reliability
If virus detection software is used, then known viruses can be detected, but unknown viruses cannot be prevented
Solution Approach 1:
Instead of relying on signature-based detection that only works for known viruses, the system performs preliminary analysis of the storage device's connection patterns and usage states before virus infection can occur. This proactive approach enables detection and prevention of both known and unknown viruses by identifying suspicious behaviors rather than relying on virus signatures

AI summary
An erasing device includes: a first connector that is detachably connected to a storage device; a second connector that is detachably connected to an information processing device; a data eraser that erases information stored in the storage device after the storage device and the information processing device are connected to one another; and an access controller that, after the information stored in the storage device is erased by the data eraser, brings the information processing device from a state where the information processing device cannot access the storage device into a state where the information processing device can access the storage device.
