Terminal-Device Network Switching for Secure Responsive Job Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between a device and a detachable terminal experiences reduced responsiveness and security discrepancies due to mismatched network settings and inappropriate path selection when the terminal is attached or detached, leading to inefficient server access and increased processing load.
Innovation Solution
An information processing system that dynamically adjusts network settings based on the attachment state of the terminal, using first network settings when attached and second network settings when detached, which include security levels and communication paths tailored to the device's security requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encrypted communication and encrypted DNS are always applied to maintain security, then security level is improved, but communication responsiveness deteriorates due to large processing load and external server access
Solution Approach 1:
The patent applies dynamics by making the communication path selection adjustable based on terminal attachment state. When the terminal is attached, direct communication is used; when detached, network communication with appropriate security settings is selected. This dynamic adaptation resolves the contradiction by optimizing both security and responsiveness according to operational context.
Solution Approach 2:
The patent applies local quality by setting different security levels for different communication scenarios. Local communication (terminal attached) uses one security configuration, while remote communication (terminal detached) uses another. This allows security to be appropriately applied only where needed, improving responsiveness without compromising essential security.
2Productivity
If communication is performed using network setting information set in the terminal, then communication responsiveness is improved, but security discrepancies occur due to mismatched network settings
Solution Approach 1:
The system dynamically switches between using terminal network settings (when attached for responsiveness) and device network settings (when detached for security consistency). This dynamic selection based on attachment state resolves the contradiction between responsiveness and security consistency.
Solution Approach 2:
The device acts as an intermediary that provides network setting information to the terminal. When the terminal is detached, the device's network settings serve as the intermediary configuration, ensuring security consistency while enabling remote communication.
3Adaptability or versatility
If independent communication paths are established for operation communication and other communication when terminal is detached, then communication functionality is improved, but security control deteriorates due to inability to enforce device security settings
Solution Approach 1:
The device's network setting information storage unit serves multiple functions: it stores network settings for both direct terminal communication and remote communication. This multi-functionality allows the same security-configured settings to be applied universally across different communication modes, resolving the contradiction between functionality and security control.

AI summary
An information processing system includes a processor and a memory, in which the processor is configured to: in a case where a terminal transmits a request to execute a job to a device that the terminal is attachable to and detachable from, in a state in which the terminal is attached to the device and the device and the terminal are connected to each other, control the terminal such that the terminal requests the device to execute the job indicating that communication is performed using first network setting information set in the device; and, in a state in which the terminal is detached from the device and the device and the terminal are disconnected from each other, control the terminal on the basis of the job such that the terminal requests the device to execute the job indicating that communication is performed using second network setting information that is stored in the memory, is different from the first network setting information, and includes network settings related to communication corresponding to a security level of each of plural networks having different security levels.
