Printing Apparatus Multi-Factor Authentication Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a security risk in printing apparatuses where multi-factor authentication settings can be changed from one authentication service to another, potentially deactivating multi-factor authentication, allowing unauthorized access without performing the required authentication factors.
Innovation Solution
The printing apparatus includes separate authentication units for local and remote access, ensuring that multi-factor authentication is not deactivated from remote access if it is activated for local access, and vice versa, thereby preventing unauthorized login and reducing security risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multi-factor authentication settings can be changed from one authentication service to another, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent segments the authentication system into separate authentication services (local access service and remote access service), each with independent multi-factor authentication settings. This allows the system to manage security settings for different access methods separately, preventing a change in one service from affecting another, thus resolving the contradiction between ease of operation and security.
2Ease of operation
If multi-factor authentication is deactivated for remote access, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent implements preliminary anti-action by detecting when multi-factor authentication is deactivated for one access service and proactively preventing deactivation for other services. The control unit monitors authentication setting changes and automatically maintains multi-factor authentication status across different services, countering potential security compromises before they can occur.
3Reliability
If separate multi-factor authentication settings are maintained for different access methods, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent applies universality by implementing a centralized control unit that manages multiple authentication services with a unified security policy. The control unit provides multi-functional capabilities by monitoring and coordinating authentication settings across different access services, allowing the system to maintain separate settings while being managed through a single universal control mechanism, thus reducing perceived complexity.

AI summary
An image forming apparatus including a function including at least a print function includes a first authentication unit configured to perform authentication processing on local access to the image forming apparatus, a second authentication unit configured to perform authentication processing on remote access to the image forming apparatus, and a reception unit configured to receive separately a setting to activate multi-factor authentication processing including a plurality of authentication factors in the authentication of the local access and a setting to activate multi-factor authentication processing including a plurality of authentication factors in the authentication of the remote access. In a case where the multi-factor authentication processing for the local access is activated and the multi-factor authentication processing for the remote access is not activated, the activated multi-factor authentication processing for the local access is controlled not to be deactivated from the authenticated remote access.
