Storage Controller Segmentation for Unregistered User Data Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In document management systems, unregistered users cannot prevent others from reading their stored data when files are shared from the same storage area, leading to inconvenience and impractical storage requirements.
Innovation Solution
An information processing apparatus with a storage controller that associates unregistered users with unique identification information, such as URLs or cookies, to differentiate and secure their data, and a display controller that switches displayed data based on this identification, ensuring only the user's data is accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data items are accepted from unregistered users and stored in the same storage area, then storage efficiency is improved, but unregistered users can read each other's data leading to privacy loss
Solution Approach 1:
The patent segments the storage area by creating separate storage spaces for each unregistered user, identified by unique identification information. This allows multiple users to store data in the same overall storage area while maintaining individual privacy, as each user can only access their own segmented storage space.
Solution Approach 2:
The patent introduces identification information (such as URLs or cookies) as an intermediary between the storage system and unregistered users. This intermediary enables the system to distinguish between different users and control access accordingly, allowing storage efficiency while preventing unauthorized reading of other users' data.
2Ease of operation
If unregistered users are allowed to store data without registration, then ease of operation is improved, but data security control becomes difficult
Solution Approach 1:
The patent enables unregistered users to store and access their own data without requiring registration or login credentials. The system automatically assigns identification information to each user's device, allowing them to self-serve their data storage needs while maintaining security through device-based identification.
Solution Approach 2:
The patent changes the authentication parameter from user-based (registration/login) to device-based (identification information associated with computing devices). This parameter change maintains ease of operation for unregistered users while improving data security control through consistent device identification.

AI summary
An information processing apparatus includes a storage controller and a display controller. The storage controller performs control when storing of data is accepted from an unregistered user yet to be registered in advance. The control is performed to store the accepted data in association with identification information that enables the unregistered user to be discriminated from a different unregistered user. The display controller performs control when the unregistered user performs access to the information processing apparatus. The control is performed to switch data to be displayed to the unregistered user performing the access. The data is switched by using the identification information.
