Authentication Control for Multi-Function Peripheral Restricted Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing systems face challenges in improving user convenience when operating restricted functions of multi-function peripherals, as existing solutions either require unnecessary authentication or indiscriminately disable user operations, leading to inefficiencies and potential quality issues in print products.
Innovation Solution
An information processing system with a multi-function peripheral that includes an authentication unit for verifying administrator information and a control unit to manage screen operations, allowing users to perform authenticated operations on restricted functions while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is required via the console section when operating restricted functions from the information processing apparatus, then authorized users can access restricted functions, but users without authority experience troublesomeness due to frequent authentication screen display
Solution Approach 1:
The system performs preliminary authentication by transmitting administrator information from the information processing apparatus to the multi-function peripheral before the user operates restricted functions. The multi-function peripheral stores this authentication result and uses it to determine whether to allow operation of restricted functions, eliminating the need for repeated authentication screens.
Solution Approach 2:
The invention introduces an intermediary authentication mechanism where the information processing apparatus transmits administrator information to the multi-function peripheral, which then acts as an intermediary to control access to restricted functions based on this pre-transmitted authentication data, rather than requiring direct console authentication.
2Reliability
If the information processing apparatus indiscriminately disables user operations on restricted functions, then unauthorized operations are prevented, but authorized users cannot set adjustment items from the information processing apparatus
Solution Approach 1:
The system performs preliminary authentication by transmitting administrator information from the information processing apparatus to the multi-function peripheral before the user operates restricted functions. The multi-function peripheral stores this authentication result and uses it to determine whether to allow operation of restricted functions, eliminating the need for repeated authentication screens.
Solution Approach 2:
The system changes the authentication parameter state by transmitting administrator information that indicates whether the user is authorized. The multi-function peripheral changes its operational state based on this parameter, allowing restricted functions to be accessible when the parameter indicates authorized status while maintaining protection when unauthorized.

AI summary
A multi-function peripheral and an information processing apparatus are capable of communicating with each other. In one authentication setting of the information processing apparatus, functions restricted in use are disabled from being set. In another authentication setting of the information processing apparatus, when an operation on a function restricted in use is performed on a screen associated with functions of the multi-function peripheral, the information processing apparatus displays an authentication screen to cause the multi-function peripheral to execute an authentication process based on information input via the authentication screen, and if a result of the authentication process transmitted from the multi-function peripheral indicates that the authentication is successful, the screen is controlled to receive the operation on the function from the user.
