Image Forming System Configuration Export Import via USB
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses require password information to be included in an instruction information file for importing configuration information, necessitating users to prepare and store an instruction file with password data, which complicates the process and may compromise security.
Innovation Solution
The system allows configuration information to be exported and imported between image forming apparatuses without the need for instruction information, using a USB memory to store configuration files and authenticating using device and data passwords, enabling secure and user-friendly duplication of settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password information is included in an instruction information file for importing configuration information, then authentication can be performed, but the user must prepare and store an instruction file with password data which complicates the process and may compromise security
Solution Approach 1:
The patent extracts the password authentication mechanism from the instruction information file. Instead of including password data in the configuration file, the system separates authentication (performed via authentication screen UI) from configuration import, eliminating the need for users to handle password-containing files while maintaining security.
Solution Approach 2:
The patent introduces an intermediary authentication screen that mediates between the configuration file and the import process. The authentication screen acts as a secure gateway that verifies user credentials before allowing configuration import, replacing the insecure method of embedding passwords in files.
2Reliability
If instruction information file with password data is required for configuration import, then authentication is enabled, but users must prepare and store instruction files which increases device complexity
Solution Approach 1:
The patent removes the instruction information file requirement entirely. Authentication credentials are obtained through the authentication screen interface rather than being embedded in external files, eliminating the complexity of file preparation, storage, and management while maintaining authentication capability.
Solution Approach 2:
The system provides self-service authentication through the authentication screen, where users directly input credentials without needing to prepare external instruction files. This eliminates the complexity of file management while enabling authentication.
3Reliability
If password information is stored in text format in instruction files, then authentication can be performed, but security is compromised
Solution Approach 1:
The patent extracts password information from text-based instruction files and implements authentication through a secure screen interface. This eliminates the security vulnerability of storing passwords in text format while preserving the authentication function through UI-based credential input and verification.
Solution Approach 2:
The authentication screen serves as a secure intermediary that handles credential verification without exposing password data in text format. It mediates between user input and system authentication, preventing the security vulnerability of text-based password storage while maintaining authentication functionality.
Data Source
AI summary
An image forming system including first and second image forming apparatuses each including a controller, a media interface, a memory, and a user interface. When configuration information is not stored in a recording medium connected to the media interface of the first image forming apparatus, the controller of the first image forming apparatus encrypts configuration information stored in the memory of the first image forming apparatus using a data password received via the user interface of the first image forming apparatus, and exports the encrypted configuration information to the recording medium. When configuration information is stored in a recording medium connected to the media interface of the second image forming apparatus, the controller of the second image forming apparatus decrypts the configuration information stored in the connected recording medium using a data password received via the user interface of the second image forming apparatus, and imports the decrypted configuration information.
