Routing Device for Cross-Provider User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems face challenges in centrally managing personal information across multiple services, leading to difficulties in authenticating users when their data is not managed by a single server device.
Innovation Solution
A routing device that communicates with center devices to store and manage linking information between attributes and users, allowing it to acquire the relevant attribute for a user and request authentication from the corresponding center device, enabling authentication even when the user's data is not managed by the initial center device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If personal information is centrally managed by one server device, then authentication efficiency is improved, but system adaptability deteriorates when user data is distributed across multiple services
Solution Approach 1:
The patent introduces a routing device as an intermediary between the authentication server and multiple service provider systems. This routing device stores linking information that maps users to their respective attribute data locations, enabling the authentication server to efficiently route authentication requests to the correct data sources without requiring centralized storage of all user information.
2Adaptability or versatility
If user data is distributed across multiple service provider systems, then system adaptability is improved, but authentication complexity increases
Solution Approach 1:
The routing device performs preliminary action by pre-storing linking information that associates users with their attribute data locations before authentication is needed. This pre-established mapping allows the authentication server to quickly determine where to find user data without complex real-time discovery processes, reducing authentication complexity while maintaining support for distributed data across multiple services.
3Ease of operation
If centralized management of personal information is implemented, then ease of operation is improved, but information security deteriorates when sensitive data is accessed across services
Solution Approach 1:
The patent segments personal information into different attribute data sets stored at different service provider systems based on sensitivity and service requirements. The routing device manages these segmented data locations, allowing the authentication server to access only the specific attributes needed for authentication rather than centrally storing or accessing all user information, thereby improving information security while maintaining ease of operation.

AI summary
A routing device communicable with a first center device and a second center device related to providing a service to a first vehicle linked with a first user and a second vehicle linked with a second user is provided. The routing device is configured to store first linking information that links a first attribute and a first user belonging to the first attribute, and second linking information that links a second attribute and a second user belonging to the second attribute, acquire the second attribute corresponding to the second user, and request the second center device corresponding to the second attribute to perform an authentication process of the second user.
