External Storage Medium Security via Extraction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing external storage medium devices, such as locking with keys or passwords, fail to allow instantaneous removal during emergencies and are complex, leading to unauthorized access and data security risks.
Innovation Solution
An external storage medium management system comprising a device with a data holding unit, medium management unit, extraction detection unit, and access control unit that verifies authentication and inhibits data access upon removal from an enclosure, using biometrics authentication and a timer to ensure secure and instantaneous management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keys or passwords are distributed to multiple persons to enable emergency removal, then the device can be taken out in emergencies, but the risk of key theft and loss of responsibility tracking increases
Solution Approach 1:
The system implements automatic feedback by detecting medium extraction and instantly notifying the manager through communication devices. This real-time feedback mechanism eliminates the need for manual key distribution while maintaining security, as the manager is immediately informed of any removal activity regardless of who performs it.
Solution Approach 2:
The extraction detection unit automatically detects when a medium is removed and triggers the notification system without human intervention. This self-service approach replaces manual key management with automated detection and reporting, reducing security risks associated with key distribution.
2Ease of operation
If keys or passwords are distributed to multiple persons to enable emergency removal, then the device can be taken out in emergencies, but the complexity of key management and responsibility tracking increases
Solution Approach 1:
The invention extracts the security management function from manual key distribution to an automated detection and notification system. The extraction detection unit monitors medium removal and the notification unit communicates with the manager, completely eliminating keys and passwords from the system while reducing management complexity.
Solution Approach 2:
The system performs self-service by automatically detecting extraction events and notifying the manager without requiring manual key management procedures. This automation eliminates the complexity of distributing, tracking, and managing physical or digital keys among multiple persons.
3Reliability
If conventional locking mechanisms are used, then data security is maintained, but the ability to instantly detect and respond to unauthorized removal is delayed
Solution Approach 1:
The system implements immediate feedback by detecting medium extraction through the detection unit and instantly notifying the manager through communication devices. This real-time feedback eliminates the time delay inherent in conventional locking mechanisms, enabling instantaneous detection and response to unauthorized removal while maintaining data security through subsequent access control.
Solution Approach 2:
The access control unit is pre-configured to inhibit data access automatically upon detection of medium extraction. This preliminary action ensures that even if the medium is removed, data security is maintained through automated access inhibition, eliminating the need for manual intervention and reducing response time.

AI summary
An external storage medium management system takes into account the maintenance of data security in case an external storage medium has been taken out on emergency. It comprises an external storage medium device and an enclosure device, which is connected to a host side device and which accommodates the external storage medium device, the external storage medium device reports the result of authentication to the enclosure device in case authentication operation is done. On detection of extraction of the external storage medium device from the enclosure device, the external storage medium device of inhibits access to retained data and allows access to the data only in case the authentication in accordance with a preset system has met success. In case the enclosure device also has detected the extraction of the external storage medium device by a medium extraction detection unit, the enclosure device announces the status prevailing at the time of the extraction (authentication coincidence/non-coincidence/authentication data invalid/no authentication data) to the host side.
