Selective Storage Partition Mounting for Data Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack an efficient method to manage and control access to multiple storage areas based on different authority levels, leading to potential data security breaches and access complexities.
Innovation Solution
An electronic device is designed to identify user inputs and switch between different modes of operation, where a first mode associates all storage areas with directory names, and a second mode selectively mounts only specific areas based on second authority information, thereby controlling access and isolating sensitive data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all storage areas are associated with directory names in the first mode, then access to storage areas is simplified and convenient, but data security is compromised because unauthorized access to sensitive information becomes possible
Solution Approach 1:
The patent segments the storage areas into multiple partitions, where each partition can be independently mounted or unmounted. This allows the system to selectively associate directory names with only certain storage areas (first partition) while leaving others (second partition) unassociated, thereby maintaining ease of access for general storage while protecting sensitive data in segregated partitions.
2Reliability
If the electronic device switches to the second mode to selectively mount storage areas, then data security is enhanced by preventing unauthorized access, but access management complexity increases
Solution Approach 1:
The patent implements a dynamic mounting mechanism that allows the system to switch between different mounting states based on operational requirements. In the first mode, all storage areas are mounted for convenient access. In the second mode, only specific partitions are mounted while others remain unmounted for security. This dynamic approach enables flexible security management without requiring complex permanent configurations.
3Reliability
If the electronic device turns off and on to switch between modes, then complete disassociation and reassociation of storage areas is achieved, but time loss occurs during the boot process
Solution Approach 1:
The patent implements preliminary mounting configurations that are established during the boot process itself, rather than requiring a complete shutdown and restart. The system pre-configures which partitions should be mounted based on the operational mode, allowing the mounting control to be executed as part of the normal boot sequence without requiring additional time-consuming cycles of complete power off and on.

AI summary
At least one processor of an electronic device according to an embodiment may turn off the electronic device, on the basis of an input identified while directory names are associated with storage areas of the memory on the basis of a first mount operation within a first mode of the electronic device, such that the directory names are dissociated from the storage areas, and may turn on the electronic device in order to boot same in a second mode. The processor may identify a part of the storage areas in which log information is stored while the electronic device is booted in a second mode. The processor may perform a second mount operation in order to associate a part of the directory names with the part of the storage areas while the remaining part of the storage areas is disassociated from the remaining part of the directory names in order to deactivate access to information stored in the remaining part of the storage areas.
