Apparatus Maintenance Data Access with Master-Slave Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatus maintenance management systems face security issues as users can access information from multiple apparatuses, compromising the confidentiality of data.
Innovation Solution
Implement a remote processor that uses authentication keys with a master-slave relationship to restrict communication, determining the range of information provided based on the type and relationship of the authentication keys held by communication partners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a centralized management system is used to collect information from multiple apparatuses, then information management efficiency is improved, but information security deteriorates because users can access information from apparatuses they should not access
Solution Approach 1:
The patent segments the centralized information system into multiple isolated virtual spaces, each corresponding to a specific apparatus or user group. The virtualization unit creates separate virtual information management systems that prevent cross-access between different apparatus information, thereby maintaining security while preserving centralized management efficiency.
Solution Approach 2:
The patent introduces a virtualization unit as an intermediary layer between the centralized information collection system and user access. This intermediary creates virtual copies of information with controlled access permissions, allowing efficient information management while preventing direct access to unauthorized apparatus data.
2Loss of information
If all apparatus information is made accessible to users for comprehensive monitoring, then system transparency is improved, but information confidentiality deteriorates
Solution Approach 1:
The patent applies local quality by providing different levels of information transparency to different users based on their authorized apparatus. Each user receives complete transparency for their own apparatus information while maintaining confidentiality for other apparatuses, achieving localized transparency without compromising overall system security.
3Device complexity
If centralized management provides uniform access to all users, then system simplicity is improved, but adaptability deteriorates because different users have different information needs
Solution Approach 1:
The patent implements universality by creating a virtual information management system that can adapt to different user roles and apparatus types through virtualization. The same centralized system structure serves multiple functions by dynamically creating appropriate virtual spaces and access permissions for different user-apparatus combinations, maintaining simplicity while achieving versatility.

AI summary
An apparatus maintenance management system includes a plurality of apparatuses each configured to transmit information on its own operation and information on the presence or absence of an abnormality, and a remote processor configured to acquire and store the information of each of the apparatuses. The remote processor is configured to restrict communication by using authentication keys of at least one type having a master-slave relationship, and perform communication with, as a communication partner, each of a first communication device to which one of the authentication keys that functions as a master for at least one of the apparatuses is given in advance and a second communication device to which another one of the authentication keys that functions as a slave for the first communication device is given in advance. When performing communication, the remote processor determines a range of the information to be provided to the communication partner according to the type and the master-slave relationship of the authentication key that the communication partner has.
