Image Forming Apparatus Multi-Factor Authentication Remote Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses do not support multi-factor authentication for remote access to image processing functions, particularly for protocols like Mopria, which limits the application of multi-factor authentication to remote image processing functions.
Innovation Solution
The image forming apparatus implements an authentication unit that performs multi-factor authentication for remote UI access while allowing alternative authentication processing for remote access to image processing functions that do not support multi-factor authentication, using a combination of IC card authentication, passwords, and one-time passwords generated by mobile applications or browser plugins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-factor authentication processing is applied to all remote access, then security is improved, but compatibility with protocols like Mopria deteriorates because they do not support multi-factor authentication
Solution Approach 1:
The authentication processing is segmented into different types based on protocol capabilities. The system identifies whether a protocol supports multi-factor authentication and applies the appropriate authentication method accordingly, allowing both secure multi-factor authentication for supported protocols and compatible alternative authentication for protocols like Mopria that do not support it.
Solution Approach 2:
The authentication system dynamically adjusts its behavior based on the protocol being used. When a protocol supports multi-factor authentication, the system applies it; when a protocol does not support it (such as Mopria), the system automatically switches to alternative authentication processing methods, making the system adaptable to different protocol capabilities.
2Reliability
If multi-factor authentication is enforced for remote access, then unauthorized access is reduced, but ease of operation deteriorates for protocols that do not support multi-factor authentication
Solution Approach 1:
Different authentication methods are applied to different protocols based on their local capabilities. For protocols that support multi-factor authentication, the enhanced security method is applied; for protocols like Mopria that do not support it, the authentication method is adapted to match their capabilities, ensuring smooth operation without forcing unsupported authentication mechanisms.
Data Source
AI summary
An image forming apparatus performs processing, which is different from multi-factor authentication processing, on remote access to a function on which the multi-factor authentication processing cannot be performed. In this way, remote access to an image processing function is enabled without performing the multi-factor authentication processing on the remote access.
