Unified File Access via Intermediary Authentication Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face cumbersome operations when accessing and managing files saved in external storage, such as cloud storage, as they need to perform location-specific operations, leading to increased complexity.
Innovation Solution
An information processing device and system that manages authentication and index information for both client devices and cloud storage, allowing seamless file access and management by associating first and second authentication information, and using a save location monitor to update index information and provide a unified list to clients, thereby simplifying operations across different storage locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If users access files from external storage such as cloud storage, then file storage capacity is improved, but operation complexity increases due to location-specific operations
Solution Approach 1:
The patent introduces an information processing device as an intermediary between the client device and cloud storage. This device manages authentication information for both the client and cloud storage, monitors save locations, and provides a unified file list interface. Users interact with the intermediary device using consistent operations regardless of whether files are stored locally or in the cloud, eliminating the need for location-specific operations while maintaining access to external storage capacity.
2Adaptability or versatility
If cloud storage is used to save files, then storage versatility is improved, but operational burden increases due to separate authentication requirements
Solution Approach 1:
The information processing device performs multiple functions: it manages authentication information for both client devices and cloud storage, monitors save locations across different storage types, and provides a unified file list interface. This multi-functional approach allows the system to handle diverse storage locations (local and cloud) through a single operational interface, reducing the burden of separate authentication and management procedures while maintaining storage versatility.
3Reliability
If separate authentication information is managed for client and cloud storage, then security is improved, but system complexity increases
Solution Approach 1:
The patent combines the management of first authentication information (client device authentication) and second authentication information (cloud storage authentication) into a single information processing device. This device stores both types of authentication information and manages them through unified processes, including monitoring save locations and providing file lists. By merging authentication management functions into one system, the patent maintains security through separate authentication credentials while reducing overall system complexity compared to managing separate authentication systems.

AI summary
A method includes storing first authentication information and second authentication information, the first authentication information being information for a user to access a first information processing device, the second authentication information including third authentication information and fourth authentication information, the third authentication information being information for the user to access a second information processing device, and the fourth authentication information being information for the user to access a third information processing device; acquiring first index information from the second information processing device based on the third authentication information; acquiring second index information from the third information processing device based on the fourth authentication information; and generating a list including the first index information with a first indication, and the second index information with a second indication different from the first indication.
