Authentication Information Reuse Controller for Multi-Service Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices require users to previously store and input different user IDs and passwords for each service, making it cumbersome to manage authentication information across multiple services.
Innovation Solution
An information processing device with a communication unit, display unit, and controller that allows users to select services, displays an authentication screen for inputting authentication information, transmits this information to external devices for authentication, and stores it for later use, enabling seamless authentication across services without repeatedly displaying the authentication screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is stored for each service individually, then authentication can be performed for each service, but the operation becomes cumbersome and time-consuming due to repeated input requirements
Solution Approach 1:
The patent implements a universal authentication information storage mechanism where authentication information stored for one service can be automatically reused for other services. The controller determines whether stored authentication information can be applied to the currently selected service, eliminating the need for separate authentication inputs for each service while maintaining secure authentication capabilities across multiple services.
Solution Approach 2:
The system performs preliminary authentication by storing authentication information in advance during an initial authentication process. When the same authentication information is needed for another service, the controller checks the storage and automatically transmits the pre-stored information, avoiding repeated authentication inputs and reducing operation time.
2Ease of operation
If authentication information is stored for reuse, then operation convenience is improved, but security risks may increase due to stored credentials
Solution Approach 1:
The patent implements service-specific authentication information storage where authentication information is stored and managed separately for each service. The controller determines whether stored authentication information is applicable to the currently selected service, ensuring that authentication credentials are not indiscriminately reused across incompatible services while still providing convenience for legitimate reuse scenarios.
3Reliability
If authentication screen is displayed for each service selection, then authentication security is maintained, but time is lost due to repeated authentication requirements
Solution Approach 1:
The system implements a feedback mechanism where the controller continuously checks the storage for applicable authentication information when a service is selected. If matching authentication information is found, the system automatically transmits it without displaying the authentication screen. If no matching information exists, the authentication screen is displayed to collect new credentials, which are then stored for future reuse.

AI summary
An information processing device including a controller configured to accept a selection of a service from among a plurality of services including a first service and a second service, control a display unit to display an authentication screen, when accepting a selection of the first service, control a communication unit to transmit authentication information input on the authentication screen displayed in response to acceptance of the selection of the first service, to a first external device configured to perform authentication for the first service, store into a storage the authentication information transmitted to the first external device, and when accepting a selection of the second service and determining that the authentication information is stored in the storage, control the communication unit to transmit the authentication information stored in the storage, to a second external device configured to perform authentication for the second service.
