Security Information Update System for MFPs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security information update systems for image processing devices, such as multi-function printers, often result in authentication failures when password updates are not synchronized across devices, leading to device lockouts and service disruptions.
Innovation Solution
A security information update system that includes a service providing server with an authentication information memory and a policy acquisition unit in each information processing device, which acquires and updates security information based on a security policy, prohibiting service execution until the information is updated to prevent authentication failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security information is updated in all information processing devices simultaneously, then authentication reliability is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent introduces an administrative server as an intermediary that manages security information updates centrally. The server distributes updated security information to multiple information processing devices, coordinating updates without requiring direct peer-to-peer synchronization between devices. This reduces system complexity while maintaining authentication reliability across all devices.
Solution Approach 2:
The system performs preliminary actions by having the administrative server prepare and distribute updated security information before actual authentication operations occur. Devices receive update notifications and prepare for updates in advance, preventing authentication failures before they happen rather than reacting after failures occur.
2Stability of the object's composition
If security information update timing is delayed, then device operational stability is improved, but authentication failure risk increases
Solution Approach 1:
The administrative server implements a feedback mechanism that monitors whether security information updates have been applied across all connected information processing devices. The server tracks update status and can re-send update notifications or alert administrators if devices fail to update, ensuring timely synchronization while maintaining operational stability through controlled update timing.
3Reliability
If security information is updated frequently, then security reliability is improved, but loss of time for update operations increases
Solution Approach 1:
The patent merges multiple update operations into a single coordinated update process managed by the administrative server. Instead of each device independently checking and updating security information separately, the server consolidates update distribution to all devices in one coordinated action, reducing redundant operations and time loss while maintaining frequent update cycles for security reliability.

AI summary
A security information update system includes a service providing server and information processing devices, the service providing server including: an authentication information memory that stores a pair of security information and identification information; and a service providing unit that provides a service to the information processing device, and the information processing devices including: a policy acquisition unit that acquires a security policy; a security information memory that stores security information; a process executing unit that transmits a pair of the same identification information and security information to the service providing server and receives a service; an authentication information acquisition unit that acquires security information after update; an update unit that updates security information with the acquired security information after the update date and time; and a prohibition unit that prohibits execution of a process of receiving a service after the update date and time until update with the security information.
