Terminal Authentication Backup via Secondary Cloud Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud printing systems face issues with redundant registration of job-performing apparatuses due to loss of authentication-related information, leading to failed printing operations.
Innovation Solution
A terminal and method that store and backup authentication-related information in a separate storage area, allowing retrieval from a secondary cloud server if lost, preventing redundant registration and ensuring continuous printing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal stores authentication-related information only in its memory, then the storage structure is simple, but the information is lost due to user's erroneous operation or malfunction, requiring re-registration and causing redundant registration
Solution Approach 1:
A second cloud server is introduced as an intermediary backup storage for authentication-related information. When the terminal loses its authentication information, the second cloud server acts as a mediator to retrieve and restore the information, preventing redundant registration while maintaining a relatively simple terminal storage structure.
Solution Approach 2:
The authentication-related information is preliminarily backed up in the second cloud server before any potential loss occurs. This preliminary backup action ensures that when the terminal's memory is compromised, the information is already preserved elsewhere and can be quickly restored without requiring re-registration.
2Reliability
If the terminal re-registers the printer with the cloud after losing authentication information, then the authentication information can be recovered, but the same printer is registered redundantly with the cloud, causing printing failures
Solution Approach 1:
The second cloud server serves as an intermediary that prevents direct re-registration of the printer. Instead of re-registering the printer (which would cause redundant registration), the terminal retrieves the existing authentication information from the second cloud server, which mediates the restoration process without creating duplicate printer registrations.
Solution Approach 2:
The authentication-related information is copied to and stored in the second cloud server as a backup. When the terminal loses this information, it retrieves a copy from the second cloud server rather than creating a new authentication through re-registration, thus avoiding redundant printer registration while restoring access.
3Reliability
If the terminal performs full re-registration process after losing authentication information, then the authentication can be restored, but the printing service is interrupted and time is lost
Solution Approach 1:
The authentication-related information is preliminarily backed up in the second cloud server before any loss occurs. This preliminary action enables quick restoration by simply retrieving the existing backup information, rather than performing a time-consuming full re-registration process, thus minimizing service interruption time.
Solution Approach 2:
Instead of performing a complete re-registration process, the terminal quickly copies the authentication information from the second cloud server backup. This copying operation is much faster than full re-registration, restoring printing service with minimal time loss while maintaining authentication reliability.
Data Source
AI summary
According to one embodiment, there is provided a terminal that includes a memory and a processor. The memory stores authentication-related information indicating that a first cloud completes approval of authentication, which is acquired by a terminal from the first cloud that transmits an instruction to perform a job to a job-performing apparatus of which registration is completed based on an instruction from the terminal, if the registration of the job-performing apparatus is completed. The processor retains the authentication-related information in a storage area if the job-performing apparatus is registered with the first cloud, and, if the authentication-related information is not present in the memory after the approval by the first cloud, acquires the authentication-related information from the storage area.
