Image Forming Authentication for Administrator-Verified Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack effective security measures for authentication processing of maintenance users, despite regulations requiring unique passwords for user categories like administrator and maintenance users.
Innovation Solution
Implementing authentication processing that requires an administrator user's password to be set as the maintenance user's password or a random password confirmable only by the administrator, ensuring secure login and password change procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information of an administrator user is stored as authentication information of a maintenance user, then security in authentication processing is improved, but device complexity increases due to additional authentication screens and processing steps
Solution Approach 1:
The system performs preliminary authentication verification by displaying a notification screen that requests input of administrator authentication information before allowing maintenance user login. This preliminary action ensures that the maintenance user's authentication information is validated against the administrator's credentials, thereby enhancing security before the actual authentication process begins.
Solution Approach 2:
The notification screen acts as an intermediary between the maintenance user authentication process and the administrator authentication verification. It mediates the authentication process by requiring administrator credentials as a prerequisite, creating a layered security mechanism that bridges the gap between maintenance user access and administrator-level security requirements.
2Reliability
If authentication information of a maintenance user is changed, then security is maintained through updated credentials, but loss of time occurs due to the password change notification and processing
Solution Approach 1:
The system enables maintenance users to autonomously change their own authentication information through a self-service mechanism. When a maintenance user successfully authenticates, the system automatically displays a notification prompting them to change their password, allowing them to update their credentials without requiring administrator intervention or additional verification steps, thereby minimizing time loss.
Solution Approach 2:
The system provides immediate feedback to the maintenance user upon successful authentication by displaying a notification that prompts them to change their password. This feedback mechanism guides users through the password change process efficiently, ensuring they are aware of the security requirement and can complete the action without delay or confusion.

AI summary
An image forming apparatus includes a display; a one or more memories that store authentication information of a user of the apparatus; and one or more controllers that control authentication processing for the user, in which the one or more controllers: control the display such that, when authentication information of an administrator user who performs management of the apparatus is stored as authentication information of a maintenance user who performs maintenance of the apparatus, a notification that requests input of the authentication information by the administrator user is displayed on an authentication screen for the maintenance user; control the display such that, when authentication processing for the maintenance user is successful, a notification prompting a change of the authentication information of the maintenance user is displayed; and store the changed authentication information of the maintenance user when the authentication information of the maintenance user is changed.
