Solution Overview
Problem
Conventional techniques face security vulnerabilities due to the limited number of department authentication combinations, leading to low security strength, and compatibility issues when trying to implement user authentication for jobs executed from external devices, as they often default to department authentication to maintain compatibility with driver software.
Innovation Solution
An information processing apparatus and method that determines the operation mode of a multi-function peripheral to either support user authentication only or both user and department authentication, allowing for selective authentication based on user input before job execution, ensuring compatibility with conventional driver software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If department authentication is used for job execution from external devices to maintain compatibility with conventional driver software, then compatibility is preserved, but security strength is reduced due to limited authentication combinations
Solution Approach 1:
The system dynamically switches between department authentication and user authentication modes based on the authentication mode setting of the multi-function peripheral. When user authentication mode is detected, the system transitions to using user authentication; otherwise, it uses department authentication. This dynamic adaptation resolves the contradiction by allowing the system to optimize for security when possible while maintaining compatibility when necessary.
2Reliability
If user authentication is implemented for external device jobs, then security strength is improved, but compatibility with conventional driver software is reduced
Solution Approach 1:
The system automatically detects the authentication mode setting of the multi-function peripheral and adapts its authentication method accordingly. This dynamic behavior allows user authentication to be applied when the MFP supports it (improving security) while falling back to department authentication when needed for compatibility, thus resolving the contradiction between security improvement and compatibility maintenance.
Solution Approach 2:
The system changes the authentication parameter (from department authentication to user authentication) based on the detected authentication mode of the multi-function peripheral. This parameter adaptation allows the system to optimize security strength when the MFP is configured for user authentication while maintaining compatibility with driver software that expects department authentication when the MFP is configured otherwise.
3Ease of operation
If authentication mode settings are not synchronized between external devices and multi-function peripheral, then operational flexibility is maintained, but security vulnerabilities arise from mismatched authentication modes
Solution Approach 1:
The system implements a feedback mechanism where the authentication mode setting of the multi-function peripheral is detected and used to determine the authentication method for job execution. This feedback loop ensures that the authentication mode is synchronized between the external device and the MFP, preventing security vulnerabilities while maintaining operational flexibility through automatic adaptation.
Solution Approach 2:
The system automatically detects and adapts to the authentication mode setting of the multi-function peripheral without requiring manual configuration. This self-service approach synchronizes authentication modes automatically, eliminating security vulnerabilities caused by mismatches while preserving operational flexibility through autonomous adaptation.
Data Source
AI summary
It is determined that the multi-function peripheral operates according to a first mode in which user authentication is available and department authentication is not available or operates according to a second mode in which both of the user authentication and department authentication are available. In a case that the multi-function peripheral operates according to the first mode, user authentication information is transmitted to the multi-function peripheral. In a case that the multi-function peripheral operates according to the second mode, authentication information is transmitted to the multi-function peripheral. The authentication information is used to causing the multi-function peripheral to perform selection authentication before performing a job. The selection authentication is one selected from the user authentication and department authentication by a user.
