Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Acquiring log information from remote devices for error analysis is costly and time-consuming, and existing systems lack effective security measures for transmitting sensitive information.
Innovation Solution
An image forming apparatus and log information acquisition system that includes a communication processor, an external communication processor, and an approval processor to securely transmit log information from devices to a management server, with a registration processor to manage and approve the transmission of log information based on identifiers and approval flags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If log information is collected from remote devices via network, then acquisition cost and time are reduced, but security risk increases due to transmission of confidential information
Solution Approach 1:
The image forming apparatus serves as an intermediary between the management server and the remote device. It receives log information from the remote device, verifies authentication information, and conditionally transmits approved logs to the management server. This mediator role enables secure log collection without requiring direct connection between the management server and remote devices, thus reducing security risks while maintaining efficiency.
Solution Approach 2:
Authentication information is issued in advance from the management server to the image forming apparatus before log collection occurs. The apparatus stores this authentication information and uses it to verify log transmission requests. This preliminary authentication setup enables secure log acquisition without real-time security negotiations, reducing both time and security risks.
2Reliability
If authentication information is issued to each device, then security is improved, but device complexity increases due to authentication management
Solution Approach 1:
Multiple authentication functions are merged into the image forming apparatus. It handles authentication information storage, verification of multiple remote devices, and conditional log transmission approval. This consolidation reduces the authentication management burden on individual remote devices while maintaining strong security through centralized verification.
3Productivity
If all log information is transmitted without approval, then acquisition efficiency is improved, but security control is worsened due to uncontrolled confidential information transmission
Solution Approach 1:
The system implements a feedback mechanism where the image forming apparatus evaluates each log transmission request against stored authentication information and approval criteria. Only logs that pass the verification feedback loop are transmitted to the management server. This selective feedback process maintains high acquisition efficiency for approved logs while preventing unauthorized confidential information transmission.

AI summary
An image forming apparatus includes a communication processor, an external communication processor, and an approval processor. The communication processor is configured to communicate with a plurality of devices. Each of the plurality of devices is capable of generating an image forming job and configured to execute at least one software program. The external communication processor is configured to communicate with a management server. The approval processor is configured to approve transmission of log information relating to a target software program among the at least one software program. The target software program is executed by a target device among the plurality of devices in response to the target device receiving a request to transmit the log information for the target software program. The request is received by the target device from the management server.
