Group User Authentication via Pre-acquired Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing device registration procedures for new users are time-consuming and burdensome, requiring users to complete a lengthy registration process when transitioning to a new device.
Innovation Solution
An information processing device and server system that allows a first user to sign in and acquire data for associated users, enabling the display of a login screen with pre-acquired user information, thereby simplifying the registration process for subsequent users by transmitting necessary login data from the server to the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user performs the predetermined registration procedure to register themselves in a new information processing device, then the user can access the device and use services, but the registration process is time-consuming and burdensome
Solution Approach 1:
The system performs preliminary actions by acquiring user data for associated users from the server before the registration screen is displayed. The login screen generation section pre-populates the registration screen with acquired user information, so that when a user selects their information, much of the registration data is already filled in, significantly reducing the time and effort required for registration
Solution Approach 2:
The system copies user data from the server for associated users and uses this copied information to pre-populate the registration screen. Instead of requiring users to manually enter all registration information, the system retrieves and displays previously stored user data, allowing users to simply confirm or make minor adjustments to the pre-filled information
2Productivity
If the system displays a login screen with pre-acquired user information, then subsequent users can easily access the device, but the system must acquire and store additional user data from the server
Solution Approach 1:
The user data acquiring section is designed to handle multiple functions: it acquires user data not only for the current user but also for associated users from the server. This multi-functional component enables the system to serve multiple users efficiently by retrieving their data in advance, supporting the display of pre-populated registration screens for various users without requiring separate manual registration processes
Solution Approach 2:
The server acts as an intermediary that stores and provides user data for associated users. The user data acquiring section communicates with the server to retrieve this data, and the login screen generation section uses the acquired information to pre-populate the registration screen. This intermediary approach allows the system to manage complex user data relationships without increasing the complexity of the local device
Data Source
AI summary
A management section 122 allows a user A to sign in to a server. A user data acquiring section 136 acquires, from the server, data regarding a user B who is associated with the user A in the server but who is not yet registered in an information processing device 10. A user data holding section 138 holds data regarding the user A and the data regarding the user B that has been acquired. A login screen generation section 124 uses data held by the user data holding section 138 and displays a login screen including information regarding the user A and information regarding the user B.
