Centralized Log Management via Virtual Leased Line
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face challenges in securely managing and recording logs across distributed systems, particularly when image processing is controlled remotely via a virtual leased line, leading to distributed and complex log management.
Innovation Solution
An image processing system that includes a first processor on an image processing apparatus and a second processor on a control apparatus connected via a virtual leased line, where the first processor transmits log information to the second processor for storage, ensuring secure and centralized log management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If logs are distributed and recorded on both control apparatus and image processing apparatus, then log information completeness is improved, but log management complexity increases
Solution Approach 1:
The patent merges distributed logs from both the control apparatus and image processing apparatus into a single centralized log storage location on the control apparatus. This allows complete log information to be collected while simplifying management, as all logs are stored in one place rather than distributed across multiple systems.
Solution Approach 2:
The patent introduces an intermediary mechanism where the control apparatus acts as a central collection point for logs from both systems. The control apparatus receives and stores logs from the image processing apparatus via the virtual leased line, serving as a mediator that consolidates distributed log data into a centralized repository.
2Reliability
If virtual leased line is established for secure communication, then security is improved, but communication complexity increases
Solution Approach 1:
The patent extracts the security function into a separate virtual leased line communication channel, isolating it from the main system architecture. This allows secure log transmission to be handled through a dedicated secure channel while keeping the rest of the system architecture simple and unchanged.
3Device complexity
If control apparatus stores all logs centrally, then log management simplicity is improved, but communication requirements increase
Solution Approach 1:
The patent implements continuous log transmission from the image processing apparatus to the control apparatus through the virtual leased line. This ensures that log information is continuously and reliably transmitted without interruption, maintaining complete log records while enabling centralized storage and management.

AI summary
An image processing system includes: a first processor that is mounted on an image processing apparatus including at least one of an image forming unit that performs processing of forming an image on a medium or an image scanning unit that performs processing of scanning an image on a medium; and a second processor that is mounted on a control apparatus that is connected to the image processing apparatus via a virtual leased line, and controls a part of at least one of the processing of forming an image on a medium or the processing of scanning an image on a medium performed by the image processing apparatus, in which the first processor is configured to: in a case where an event to be recorded in a log occurs in the image processing apparatus, transmit log information regarding the event to the control apparatus via the virtual leased line being connected or after connecting the virtual leased line in a case where the virtual leased line is not connected; and the second processor is configured to: in a case where the event occurs in the control apparatus, store log information regarding the event in a storage unit of the control apparatus; and store log information transmitted from the image processing apparatus via the virtual leased line in the storage unit of the control apparatus.
