Image Processing Device Automated Network Restoration After Threat Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote work environments, image processing devices like MFPs face challenges in quickly restoring network connections after a security threat is detected, as administrators may not be nearby to manually recover the network, leading to downtime.
Innovation Solution
An image processing device equipped with a network communicator, a hardware processor for threat detection, and separate communication paths for notification and recovery trigger information, allowing for automated network restoration via telephone line or Bluetooth communicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network connection is cut off when a virus is detected, then security threats are prevented from spreading, but the device cannot be used and network restoration takes time
Solution Approach 1:
The image processing device automatically detects threats, cuts off network connections, and restores connections without requiring administrator intervention. The device serves itself by monitoring its own security state and autonomously managing network connectivity based on threat detection results.
Solution Approach 2:
The system continuously monitors for security threats and automatically responds by cutting off or restoring network connections based on detection results. This closed-loop feedback mechanism ensures security while minimizing unnecessary network downtime.
2Reliability
If the administrator manually restores network connection, then security control is maintained, but time is lost due to remote work conditions
Solution Approach 1:
The image processing device autonomously detects threats and automatically restores network connections after threat elimination, eliminating the need for administrator intervention and reducing restoration time in remote work environments.
Solution Approach 2:
The device continuously monitors for threats and is prepared to immediately restore network connections once threats are eliminated, reducing the time loss associated with manual administrator intervention.
3Productivity
If automated threat detection and network restoration is implemented, then network downtime is reduced, but device complexity increases
Solution Approach 1:
The image processing device integrates multiple functions including threat detection, network connection management, and automated restoration capabilities within a single system, reducing the need for separate external tools and minimizing overall system complexity.

AI summary
An image processing device includes: a communicator that executes external communication via a communication path; a hardware processor that detects a threat in the image processing device, and cuts off the communication by the communicator upon detecting the threat; a transmitter that executes communication, after the hardware processor detects the threat, to transmit a notification that the threat has been detected to a defined destination via another communication path; and a receiver that executes communication to receive communication restoration trigger information via another communication path. Once the receiver receives the communication restoration trigger information, the hardware processor executes a communication control to restore the communication by the communicator.
