Data Communication Device Logout During Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data communication systems, users are inefficiently required to remain logged in to a data processing device until data processing is completed, leading to prolonged wait times and inefficiencies, especially when dealing with large data sets.
Innovation Solution
A data communication device and method that allows users to log out while data processing is ongoing, ensuring that access to external storage areas is maintained until the processing is finished, enabling users to disconnect without aborting the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users remain logged in until data processing is completed, then data processing can continue without interruption, but user efficiency decreases and wait time increases
Solution Approach 1:
The system performs preliminary authentication and establishes access rights before the user logs out. The authentication result is stored and used to maintain access permissions during the period when the user is logged out but data processing is ongoing, allowing the processing to complete without user intervention.
Solution Approach 2:
The system introduces an intermediary authentication mechanism that decouples the user's login state from the data processing authorization. The authentication server or system acts as a mediator that validates and maintains access rights independently of whether the user is currently logged in, enabling continuous processing after logout.
2Productivity
If users can log out before data processing is completed, then user efficiency improves, but access control and security may be compromised
Solution Approach 1:
Access rights are determined and stored in advance during the login authentication process. This preliminary establishment of permissions allows the system to maintain proper access control even after the user logs out, as the authentication results are preserved and applied to ongoing operations.
Solution Approach 2:
The system implements a feedback mechanism where authentication results are continuously referenced during data processing operations. Even after logout, the system checks and applies the previously authenticated access rights to ensure that only authorized operations are performed on the data, maintaining security throughout the processing lifecycle.

AI summary
A data communication device for storing image data input by scanning an original document in an external storage device includes a scanner, an inputting unit, a log-in processing unit, and a processing unit. The scanner scans an original document to input image data. The inputting unit inputs identification information. The log-in processing unit causes a user who is authenticated based on the input identification information to log into the data communication device. The processing unit performs data processing to store image data input by the scanner in an external storage device which is accessible based on the input identification information.
