Image Forming Apparatus Multi-Factor Authentication Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming apparatuses lack multi-factor authentication for remote UI access, as many PC terminals do not include IC card reading devices, making it difficult to implement IC card authentication for remote user interfaces.
Innovation Solution
An image forming apparatus with separate authentication units for local and remote access, utilizing a combination of IC card authentication for local access and a one-time password generated by a mobile application or browser plug-in for remote access, ensuring multi-factor authentication is applied differently for each access method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IC card authentication is used for local access, then user convenience is improved, but remote access cannot use the same authentication method since PC terminals do not include IC card reading devices
Solution Approach 1:
The authentication system is segmented into separate authentication units for local and remote access. The local authentication unit handles IC card-based authentication for local UI access, while the remote authentication unit handles web-based authentication for remote UI access. This segmentation allows each access method to use its most suitable authentication mechanism without requiring the other to adapt to incompatible hardware constraints.
Solution Approach 2:
Different authentication qualities are applied to different access contexts. Local access benefits from the convenience of IC card insertion, while remote access uses web-based authentication forms. The system provides locally appropriate authentication methods for each access scenario rather than forcing a unified authentication approach.
2Reliability
If multi-factor authentication is implemented for local access, then security is improved, but the complexity of authentication systems increases
Solution Approach 1:
The authentication system divides authentication processing into separate units - a local authentication unit for local UI access and a remote authentication unit for remote UI access. Each unit independently manages its own authentication factors and verification processes, reducing the complexity burden on any single component while maintaining overall system security.
Solution Approach 2:
The authentication management unit acts as an intermediary that coordinates between the local and remote authentication units. It receives authentication information from either unit and manages the overall authentication process, simplifying the architecture by centralizing control logic while allowing distributed authentication execution.

AI summary
There is provided an image forming apparatus having security against cyberattacks by establishing an authentication factor for a remote access user that is different from an authentication factor employed in multi-factor authentication of local access.
