Image Forming Apparatus FTP File Transmission Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network image forming apparatuses face security issues as users can transmit files externally, making it difficult to track and manage unauthorized file transmissions, and identify responsible users when secure files are leaked.
Innovation Solution
An image forming apparatus with a storing part and controlling part that logs and displays a file transmission and reception list using a File Transfer Protocol (FTP), including user information, file details, and statistics, allowing for user authorization and external host communication to manage and print the list.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network image forming apparatus allows users to transmit files externally through FTP, then file transmission capability is improved, but security control and tracking ability deteriorate
Solution Approach 1:
The system performs preliminary actions by establishing user authorization levels before file transmission occurs. The controlling part stores user information including authorization levels in advance, and automatically checks these authorizations during FTP operations to prevent unauthorized transmissions before they happen.
Solution Approach 2:
The system implements feedback by automatically logging all file transmission and reception operations with user identification, file names, sizes, and timestamps. This creates a traceable record that provides feedback on who performed what operation, enabling security monitoring and accountability while maintaining transmission capability.
2Reliability
If network image forming apparatus restricts user file transmission, then security is improved, but file transmission capability deteriorates
Solution Approach 1:
The system applies local quality by implementing differentiated authorization levels for different users rather than uniform restriction. The controlling part stores and enforces user-specific authorization levels that allow legitimate file transmissions while blocking unauthorized ones, thus maintaining security without unnecessarily limiting valid operations.
3Loss of information
If the apparatus stores detailed transmission logs including user passwords, then tracking ability is improved, but information security deteriorates
Solution Approach 1:
The system performs preliminary action by establishing secure storage mechanisms before storing sensitive information. The controlling part stores user passwords and authorization data in a protected manner within the storing part, ensuring that tracking information is captured with appropriate security measures already in place to prevent unauthorized access to this sensitive data.

AI summary
An image forming apparatus to supply a file transmission and reception list, and a control method thereof. The image forming apparatus may include a storing part and a controlling part to store a list of transmission and reception for transmitted and received files using an FTP (File Transfer Protocol). The file transmission and reception list may include a user name, a date of file transmission and reception, a file name, a file size, an address of a file transmitter recipient, and a user ID or password to log in an FTP server transmitting and receiving the file through the image forming apparatus.
