Authentication Information Storage Across Multiple Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems require users to repeatedly input authentication information for each device, making the process time-consuming and inefficient when accessing multiple apparatuses.
Innovation Solution
An information processing system that includes a first apparatus, multiple second apparatuses, and a server, where the first apparatus receives authentication information from a user, transmits it to the server, and receives permission information indicating which second apparatuses the user is allowed to use, allowing the authentication information to be stored and reused across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is input for each device individually, then device security and access control are maintained, but user time and operational efficiency deteriorate due to repeated input requirements
Solution Approach 1:
The system performs preliminary authentication by storing authentication information in a first apparatus (e.g., mobile device) before actual device usage. When the user approaches a second apparatus, the authentication has already been completed in advance, and the system automatically retrieves and transmits the stored authentication information, eliminating the need for repeated manual input while maintaining security verification.
Solution Approach 2:
The system introduces a server as an intermediary between the first apparatus and multiple second apparatuses. The server stores permission information linking the first apparatus to authorized second apparatuses, and mediates the authentication process by verifying and transmitting authentication information automatically. This intermediary enables centralized authentication management across multiple devices without requiring users to input credentials at each device.
2Productivity
If authentication information is stored in the first apparatus for reuse, then access efficiency to multiple devices improves, but system complexity increases due to additional storage and transmission mechanisms
Solution Approach 1:
The first apparatus is designed with multi-functionality, serving both as a user interface for initial authentication input and as a storage device for authentication information. It can communicate with multiple different second apparatuses using the same stored authentication data. The server similarly provides universal service by managing permission information for multiple device types and users, reducing the need for separate authentication systems at each device.
3Adaptability or versatility
If permission information indicates multiple second apparatuses, then user versatility and access flexibility improve, but information management complexity increases
Solution Approach 1:
Instead of creating separate authentication mechanisms for each second apparatus, the system creates a single permission information record in the server that references multiple apparatus identifiers. This permission record is then copied or referenced by the first apparatus to access any of the authorized second apparatuses. The copying approach allows a single authentication event to grant access to multiple devices without requiring complex individual permission configurations for each device.

AI summary
An information processing system includes a first apparatus, multiple second apparatuses, and a server. The first apparatus receives authentication information from a user and transmits the authentication information to the server. If the user has been authenticated in accordance with the authentication information, the server transmits, to the first apparatus, permission information that indicates two or more second apparatuses that the user is permitted to use from among the second apparatuses. The first apparatus stores the authentication information while transmitting the authentication information to the second apparatuses. If the authentication information indicates one of the second apparatuses, the one of the second apparatuses performs an operation related to use of the one of the second apparatuses.
