Password Inheritance for Multi-Region File Storage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face operability issues when accessing files stored in multiple storage regions with different passwords, as they need to remember multiple passwords for each region, especially when files are moved or copied between regions.
Innovation Solution
An access control apparatus and method that inherits at least one password from the source region when a file is moved or copied to a destination region, allowing access using the inherited password, thereby reducing the need to remember multiple passwords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passwords are set for each file storage region to secure files, then security is improved, but the number of passwords users need to remember increases, worsening operability
Solution Approach 1:
The patent applies universality by enabling a single password to serve multiple functions: it can access multiple different file storage regions (boxes) rather than requiring separate passwords for each region. The system allows setting a common password that grants access to multiple boxes, making the password system universal across different storage regions and eliminating the need to remember multiple distinct passwords.
2Adaptability or versatility
If multiple boxes with different passwords are provided for different users and purposes, then security and organization are improved, but the complexity of password management increases, worsening ease of operation
Solution Approach 1:
The patent applies merging by combining multiple password requirements into a single password. Instead of requiring separate passwords for each box, the system merges the authentication requirements so that one password can authenticate access to multiple boxes. This reduces password management complexity while maintaining the organizational structure of multiple boxes for different users and purposes.
3Adaptability or versatility
If files are moved or copied between boxes with different passwords, then file flexibility and adaptability are improved, but the need to remember multiple passwords increases, worsening ease of operation
Solution Approach 1:
The patent applies universality by enabling a single password to provide access to multiple boxes regardless of where files are located. When files are moved or copied between boxes, the common password system ensures that users can access files in any box using the same password, maintaining file flexibility while simplifying access operations.

AI summary
Disclosed is an access control apparatus controls access to a storage device and includes an access password input device that receives an input of an access password; an access control information acquiring unit that acquires access control information indicating an access password to be inputted for access; an access controller that controls access to a file stored in a file storage region, based on the inputted access password and the access control information, wherein the access controller is operable when different region access passwords are set for accessing a first file storage region and a second file storage region, respectively, to control access after a file stored in the first file storage region has been transported to the second file storage region so that at least one password that could be used to access the file in the first file storage region is inherited after transportation.
