Secured Storage Device with Hidden Disk Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage security systems are vulnerable as they can be compromised when ID and password or password alone are exposed, allowing unauthorized access and data leakage, and they often reveal the presence of encrypted areas, enticing hackers to attempt unauthorized access.
Innovation Solution
A storage system with a secured disk area that is only accessible through a digital key and password, where the existence of the secured disk area is hidden from the operating system in a deactivated state, and can be activated only by a key application using a unique digital key and user password, providing strong security through encryption and automatic locking features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional storage security systems use ID and password or password only for access control, then ease of operation is improved, but security is worsened because the entire information can be leaked when credentials are exposed
Solution Approach 1:
The storage device is segmented into a normal disk area and a secured disk area. The secured disk area is further divided into a digital key storage area and a data storage area. This segmentation isolates the security-critical digital key from the data, so that even if data is compromised, the key remains protected in a separate secured area that requires authentication to access.
Solution Approach 2:
A digital key is introduced as an intermediary between the user and the secured data. The digital key is stored in the secured disk area and is required to access the secured data. This intermediary layer ensures that even if passwords are compromised, attackers cannot access the secured area without the digital key, which is protected by the secured file system.
2Reliability
If conventional storage security systems have encrypted areas, then security is improved, but device complexity is worsened and hackers can detect the presence of encrypted areas to target them
Solution Approach 1:
The secured file system applies different quality characteristics to different areas of the storage device. The normal disk area operates with standard file system characteristics, while the secured disk area has unique properties including hidden allocation tables, encrypted data structures, and restricted access controls. This local differentiation allows the secured area to maintain high security without making the entire system complex.
Solution Approach 2:
The security-critical components (digital key storage, allocation table, data structures) are extracted from the normal file system and placed in a separate secured disk area with its own file system. This extraction isolates the complexity to only the necessary secured portions, while the normal disk area remains simple and compatible with standard operating systems.
3Reliability
If a secured disk area is created with digital key encryption, then security is improved, but ease of operation is worsened because the secured disk cannot be accessed without the digital key and password
Solution Approach 1:
The digital key is preliminarily stored in the secured disk area during the file system creation process. The secured file system is pre-configured with the digital key and encryption parameters before data is stored. This preliminary setup ensures that when data needs to be accessed, the decryption process is already prepared and can proceed efficiently without additional complexity for the user.
