Centralized User Information Storage for Multi-Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems for image forming apparatuses face challenges in efficiently managing and migrating user information across multiple devices, leading to complexities in user authentication and function usage restrictions.
Innovation Solution
An authentication system that includes a user information extraction apparatus, which extracts user information from devices and migrates it to an information processing system, allowing common user information to be stored and used across multiple devices, thereby simplifying user authentication and function access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user information is stored in each device separately, then user authentication can be performed on each device, but user information management becomes complex and requires duplicate storage across multiple devices
Solution Approach 1:
The patent merges user information storage from multiple distributed devices into a single centralized storage location. The extraction apparatus consolidates user information from first, second, and third devices into one repository, eliminating the need for duplicate storage across devices while maintaining authentication capability.
Solution Approach 2:
The centralized user information storage serves as a universal authentication source for multiple devices. Instead of each device having its own separate user information storage, a single storage system provides authentication data for all devices, reducing overall system complexity.
2Productivity
If user information is migrated to a centralized system, then management efficiency improves and duplicate storage is eliminated, but the system requires an additional information processing system for centralized storage
Solution Approach 1:
The extraction apparatus acts as an intermediary between multiple devices and the centralized information processing system. It extracts user information from various devices and transfers it to the centralized storage, managing the complexity of data migration while improving overall management efficiency.
3Adaptability or versatility
If user information is extracted and migrated between devices, then user portability across devices improves, but the authentication process becomes more complex requiring extraction and migration mechanisms
Solution Approach 1:
The extraction apparatus extracts user information from source devices and transfers it to centralized storage. This extraction mechanism enables user portability across devices by making user information accessible from a central location rather than requiring device-specific storage.
Data Source
AI summary
An authentication system, a user information extraction apparatus, and a user information migration method. The authentication system acquires user information for authenticating a user who uses a device and transmits the acquired user information to the information processing system and the information processing system stores in one or more memory common user information for authenticating a common user who uses the device and another device different from the device, receives the user information from the user information extraction apparatus, and adds the received user information to the common user information stored in the one or more memory.
