Multi-function Peripheral Access Control via Segmented User Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-function peripherals in shared environments face challenges with unauthorized private use and administrative burdens due to the need for frequent password authentication and complex setup processes for varying user permissions.
Innovation Solution
A multi-function peripheral system that allows function usage settings based on individual and public user registration information, enabling administrators to configure access without requiring password input for basic functions and reducing administrative load by using a template for setting up function permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password authentication is required for every user to use the device, then unauthorized private use can be prevented, but the operation becomes complicated and administrative load increases
Solution Approach 1:
The user群体 is segmented into two categories: individual users who require authentication and public users who do not. This segmentation allows the system to apply different authentication requirements to different user groups, preventing unauthorized use by individual users while maintaining ease of operation for public users who only need to use basic functions
Solution Approach 2:
The system dynamically adjusts authentication requirements based on the type of user and the function being accessed. Individual users must authenticate to access their authorized functions, while public users can access basic functions without authentication. This dynamic approach resolves the contradiction by making authentication requirements flexible rather than fixed
2Reliability
If individual password setup is done for each user, then function access control is achieved, but administrative burden increases significantly
Solution Approach 1:
The public user profile serves as a universal access profile that can be used by any member of the public without requiring individual setup. This universal profile provides basic function access control while eliminating the need for administrators to individually configure passwords and permissions for each public user, significantly reducing administrative burden
3Ease of operation
If all functions are made accessible without authentication, then ease of operation is improved, but private use and unauthorized access increase
Solution Approach 1:
Different authentication requirements are applied to different functions based on their sensitivity and importance. Basic functions (copying, scanning) are made accessible without authentication to improve ease of operation, while sensitive functions (fax transmission, network printing) require individual user authentication to prevent unauthorized private use. This local differentiation of access control policies resolves the contradiction

AI summary
There is provided a multi function peripheral having a plurality of functions which includes an input unit to input individual identification information, an individual information memory unit that stores individual registration information indicating whether it is allowed to use each function of the plurality of functions responsive to the identification information input into the input unit, a public information memory unit that stores public registration information indicating whether it is allowed to use each function of the plurality of functions in case that the identification information is not input, a function setup unit that sets up whether usage of each function is allowed based on the individual registration information in case that the identification information is input to the input unit, and sets up whether usage of each function is allowed based on the public registration information in case that the identification information is not input to the input unit.
